Mounting seams according to GOST ⠀

Currently, GOST 30971-2012 is in force in this area. Seams are mounting units for adjoining window blocks to wall openings. General technical conditions (instead of GOST 30971-2002). If desired and necessary, it can be studied in detail, since besides the seams themselves, there are a lot of other useful information on the installation of window blocks. ⠀
⠀
📋 But in short at the seams: ⠀
⠀
The junction of the window (balcony) block to the wall opening. ⠀

⠀
1. The central layer ⠀
2. Outer sealing layer ⠀
3. Inner sealing layer ⠀
4. Additional sealing layer ⠀
5. Low tide ⠀
6. Windowsill ⠀
⠀
📐 Also, GOST describes the requirements for sizes, according to the materials. ⠀
⠀
🗣 In our opinion, the optimal width of the seam, from the point of view of heat engineering, ease of installation and convenience of further internal and external decoration is 20-30 mm. ⠀
⠀
🗣 In single-layer walls, in places where windows are installed, in addition to the installation joint of 20-30 mm, it is recommended to make grooves and install insulation in them. As a result, the width of the installation joint is designed to prevent freezing of the window and the window-slope assembly, and not to simplify installation for installers. ⠀
⠀
Layered joint construction: ⠀
⠀
🔸 main - providing thermal insulation and sound insulation; ⠀
🔸 external - ensuring the free exit of steam from the seam and protection of the main from external influences (UV, wind, moisture); ⠀
🔸 internal - vapor barrier, protection. ⠀
⠀
Whatever materials are used in the construction of assembly joints, they must ensure tightness and prevent freezing of the circuit. And also to be durable and resistant to operational loads. ⠀

Choosing a restaurant name ⠀

Choosing a restaurant name ⠀
⠀
Both world and our national practices go in the choice of restaurant names in various ways: ⠀
⠀
💡 historical and traditional: ⠀
⠀
1) by the name of the owner, for example, well-known in Russia at the turn of the 19th-20th centuries TESTOVA restaurant, ⠀
⠀
2) at the location, for example, in Moscow, the restaurant "MOSCOW", in the Vladimir region the restaurant "SUZDAL", ⠀
⠀
3) taking into account the specifics of the cuisine, national characteristics, clientele, for example, “THREE GUNS”, “UKRAINE”, “RUSSIAN FISH”, “ACTOR”, “ARCHITECT”, respectively; ⠀
⠀
💡 traditional: ⠀
⠀
1) in accordance with the company name of the owner company, for example, “MACDONALDS”, ⠀
⠀
2) using well-known geographical names, for example, in Moscow - “ARAGVI”, “PILSEN”, “PRAGUE”, ⠀
⠀
3) using historical roots, for example, “OLD ARBAT”, “TRAFFIC AT YELISEEV”, “WALK OUT”, ⠀
⠀
4) using the names of famous personalities and / or literary heroes, for example, “TURGENEV,” “UNCLE GILAYA,” “STANISLAVSKIY”; classic: restaurants “METROPOL”, “SAVOY”, “NATIONAL”; ⠀
⠀
💡 by name of owner: “BY IVANYCH”, “BY LEO”, “BY ALEXANDER”; ⠀
⠀
💡 fantasy: “FLOWERING GARDEN”, “BLUE BIRD”, “FURNACE STORES”; ⠀
⠀
💡 fabulous and literary: “THE LION HEART”, “SHAHEREZADA”, “THREE RICHERS; ⠀
⠀
💡 nostalgic - using famous images from a previous life in the new homeland, for example, in the suburbs of New York Brighton Beach, the restaurants ODESA, VLADIMIR ... ⠀
⠀
▪ The given classification is author's and does not exhaust the whole variety of ways of approaching the choice of names - the purpose of the given classification is to show the variety of approaches to this very difficult issue. The chosen name of the restaurant can be used as the company name or its element - in this case, legal protection comes in accordance with Art. 54 of the Civil Code of the Russian Federation regarding the brand name. Trademark protection is more effective for 42 and other classes of ICGS. ⠀

Функционал монтажных швов

Functional assembly joints

In addition to the characteristics of the design itself, proper installation is no less important, either on your own or with the assistance of craftsmen, the main thing is compliance with the technology. The main attention is often paid to the reliable fixation of the block in the opening and the ideal plane, while the seam, “zapenil, closed, forgot”. Despite the fact that high-quality installation seams, this is the key to the tightness of the opening and trouble-free operation of the window for many years. Consider why seams matter, GOST, as well as recommendations. ⠀
⠀
🚧 To consider the assembly seam simply as a gap around the perimeter of the window that needs to be filled with foam, with PSUL (pre-compressed sealing tape) or without, and close (platbands, nashchelniki, plaster, etc.) - wrong. ⠀
⠀
☝ This is a technological gap with regulated parameters and a number of functions. ⠀
⠀
💡 Everything is very simple. A mounting seam isolates the wall from the window. The temperature of the wall at the installation site of the window is lower than that of the window itself and so that the window frame does not receive minus from the wall and an assembly seam is needed. The most important purpose of the installation joint is to separate two materials that are different in thermal conductivity. ⠀
⠀
Filling, whether it is mounting foam or something else, ensures tightness: ⠀
⠀
🔸 protects against blowing ⠀
🔸 isolates the room from external atmospheric influences ⠀
🔸 prevents the outflow of warm air from the room ⠀
🔸 and also, the window block with an aperture is ит friendly ⠀
⠀
The most moody place is the docking of materials of different nature. Foam, which is better than these materials in thermal physics, helps here. ⠀
⠀
🔶 The most important parameter of the installation joint is the width. ⠀
⠀
⚠ IMPORTANT: the dimensions of the mounting seam are regulated by the state standard, and not by the installers. ⠀
We will talk about this in the next post! ⠀

Оформление ресторана

Restaurant decoration

Layout and layout ⠀
⠀
There are rules, adhering to which, you can make the most optimal use of a room designed for a restaurant, but you understand perfectly well that it is impossible to foresee everything. And of course, rules cannot be dogma. The atmosphere of your restaurant should correspond to the special menu that you are going to offer visitors. Do not forget that: It all starts with the menu, and not with the interior design. Before discussing with the designer the problems associated with the layout of the restaurant, it is necessary that he have a good idea of what you have in mind and understand what is required of him. Of course, he does not have to understand marketing, be able to make a menu and choose the type of service, know the technology of cooking, but he must have complete information about this. ⠀
⠀
📋 The list of necessary information includes: ⠀
⠀
🔸 characteristic of the local restaurant market ⠀
🔸 restaurant hours ⠀
🔸 customer category ⠀
🔸 menu type ⠀
🔸 service style ⠀
🔸 number of seats ⠀
🔸 customer flow (restaurant patency) ⠀
🔸 average number of guest groups ⠀
🔸 fluctuations in demand (daily, weekly, seasonal) ⠀
🔸 cooking technology ⠀
🔸 bar (will it serve guests) ⠀
🔸 details of service stations ⠀
🔸 functions of manager, head waiter, cashier ⠀
🔸 level of purchases Food & Beverage ⠀
🔸 number of staff ⠀
🔸 average estimated expenses for interior decoration ⠀
🔸 economic forecasts ⠀
🔸 estimate ⠀
⠀
Based on this data, you have to discuss four main topics with the designer: ⠀
⠀
✅ interior ⠀
✅ optimal layout ⠀
✅ prompt service ⠀
✅ appearance ⠀
⠀
When designing a restaurant, one should not proceed from the aesthetic views of the designer or, even worse, the owner of the restaurant: it is necessary to be based solely on logical requirements and gastronomic features. ⠀
⠀
❗ Your duty is to guarantee your guests comfort and peace, and to your employees - freedom of movement necessary for the successful completion of the work. ⠀

Можно ли обойтись без фильтра⠀

Is it possible to do without a filter?

Some people generally doubt the appropriateness of installing a filter: since water for drinking or cooking from your well is not suitable, it is better to take it in stores, from a spring, and bring it from friends. It will be more reliable and cheaper. ⠀
⠀
⠀
⚠ Cheap filters will not clean the salt, and expensive filters will ruin, and it’s not a fact that they will normally clean. And the coefficient of their cleaning decreases every day until the next cartridge is replaced or the cleaning ingredients are refilled. ⠀
⠀
🗣 But, as our expert says, salts from water are completely removed and it is not necessary, they are necessary for our body. It is necessary to remove harmful and toxic substances, and the filter copes with this task perfectly if: ⠀
⠀
▪ choose it correctly; ⠀
▪ regularly replace cartridges (the cost of the kit is 100% in any case lower than the cost of the corresponding volume of bottled water). ⠀
⠀
The springs are affected by all the problems of the wells; they may contain various non-specific contaminants that cannot be detected with the naked eye. ⠀
⠀
🌊 If you regularly visit the spring, we recommend that you first take the analysis from it to the laboratory, and check at least 15 parameters. Most important: microbiology and organics, hardness, iron, manganese, nitrates, fluorides. In our experience, MPCs for nitrates are exceeded in more than 60% of springs, and in regions with active agricultural activity - by 100% .⠀
⠀ ☝ Conclusions: ⠀
⠀
So, when choosing a filter for washing, it is important that it is suitable specifically for your water. Therefore, first of all, you need to do an analysis, and then look at exactly what flaws need to be addressed.
⠀
➖ bad smell and color of water ⠀
➖ scum ⠀
➖ metallic taste and “rusty water” ⠀
➖ bacteria ⠀
⠀
Each problem is solved by a specific filter. ⠀
⠀
👍 It is also important that the name of the manufacturer is known - this means that he cares about his reputation, and the filter design is reliable and extremely easy to use.

Сорбционные фильтры или обратный осмос?

Sorption filters or reverse osmosis?

Flow-through filters for washing are valued, first of all, for the speed of cleaning - consumers instantly get clean water. ⠀
⠀
🗣 Flow filters have two different cleaning principles. The first is sorption filters. They contain in various sorbents (coal, ion-exchange resin), which adsorb pollution on its surface. The second type is reverse osmosis filters with a membrane whose pores are passed only by water molecules. On this membrane, the water flow is divided into two parts: 20-25% goes to a tap of clean water, the rest goes to drainage. ⠀
⠀
❓ Which system is better? ⠀
Both have strengths and weaknesses. ⠀
⠀
The strong side of reverse osmosis is that it can purify water of virtually any initial composition to the H2O state. There is no alternative to reverse osmosis if you have a very high level of iron in your water (above 1.5 mg / l), nitrates or fluorides, a risk of radioactivity or microbiological contamination, including viruses. ⠀
⠀
➖ At the same time, according to the expert, this design has a number of disadvantages: ⠀
⠀
▪ Water after reverse osmosis filters is absolutely “empty”, it does not contain not only harmful but also useful substances. The use of such water without additional mineralization for a long time is unsafe for health ⠀
▪⠀
Water consumption increases four times, since only one part of the water falls into the tap, and 3-4 parts into the drain ⠀
▪ To “push” water through the membrane, a pressure of at least three atmospheres is required. If there is no such pressure in the pipes, a pump and electricity supply are required ⠀
▪ Such systems are more expensive ⠀
⠀
👍 Unlike reverse osmosis filters, sorption filters can clean ⠀
water only from those contaminants for which sorbent is in their composition. ⠀
⠀
👍 In this list, all pollution typical of tap water: chlorine and its compounds, iron and heavy metals, odor, color, suspended solids, hardness up to 6 mEq / l. At the same time, such filters are cheaper and less sensitive to water pressure at the inlet and leave macronutrients necessary and useful for the body in the water.

Features of water filters

According to our expert, without analysis, only a few of the most obvious problems can be identified. They are collected in a small cheat sheet. ⠀
⠀
▪ Problem - ▫ Symptoms ⠀
⠀
▪ Availability of suspended particles - ▫ Turbid opalescent water ⠀
⠀
▪Hardness - ▫ Quickly formed scale on the teapot and film on hot drinks ⠀
⠀
▪ Iron - ▫ The water has a yellow coating and forms smudges on the plumbing ⠀
⠀
▪Sulfide - --Specific smell of rotten eggs ⠀
⠀
The problem is that most highly toxic substances (nitrates, fluorine, heavy metals) cannot be detected ⠀
by eye or by improvised means. Better to do a full water analysis. ⠀
⠀
💦 Features of filters for washing ⠀
⠀
Unwanted impurities can be eliminated from water at home by placing a three-stage drinking water purification system under the sink and connecting to the house’s water supply pipe (or cold water main). A separate faucet for purified water will need to be inserted into the sink or countertop. Water, passing through all three stages of purification in succession, gets rid of mechanical impurities, chlorine and organic and organochlorine impurities, heavy metals, undesirable tastes and unpleasant odors. ⠀
⠀
⠀
🌊 There are various options for completing a flow filter, and, depending on them, you can reduce the iron content and water hardness, as well as get rid of bacteria. ⠀
Self-locking systems have now been developed that do not allow filter elements to unscrew when the filter is even under strong pressure. Using the instructions, such a filter can be installed independently, in just half an hour. ⠀
⠀
Many are annoyed by the need to often change cartridges, but modern filters are designed so that there is no problem - all with one touch. There is no need to use a special key, rinse flasks and perform other tedious rituals. ⠀
⠀
⚠ The easiest way to change the cartridges is in a three-stage cleaning system - the operation takes 30 seconds and can be performed with one hand. Importantly, before replacing, do not forget to shut off the water! ⠀

Современное кухонное оборудование

Modern kitchen equipment

We continue our review: ⠀
⠀
👽 Salamander ⠀
⠀
This is a traditional equipment (a type of grill), which should be present in a modern kitchen. In salamanders, heating elements are located above the products, so they are especially convenient to use to bring the product to a ready to serve: for crusting or warming up already prepared dishes. Gas and electric models give the same results. It is the perfect machine for a la carte kitchens and prefab kitchens. ⠀
⠀
❄ Product quick cooler ⠀
⠀
This unit is a refrigerator that uses forced ventilation to ensure quick cooling. It provides a freezing temperature of -18 ° C and is equipped with a probe with a display that allows you to measure the temperature inside the product. It is used to quickly cool cooked foods, as well as pre-cooked dishes and pastries, so that they can then be stored at low temperatures. For example, in the United States of America already from the beginning of the 1980s, and in Italy - from the beginning of the 1990s, it was impossible to obtain a license to open a restaurant without this equipment. ⠀
⠀
💨 Combi ovens / combi steamers ⠀
⠀
Steam convection ovens operate in various modes. With their help, you can cook food for a couple, fry, boil, as well as heat the finished dishes. Their control is carried out in two ways: electromechanical and electronic (computer). Steam convection ovens operate in various temperature conditions - from 50 to 300 ° С - with a variable humidity coefficient depending on the method of cooking. ⠀
⠀
✨ Vacuum equipment ⠀
⠀
This equipment can be used both for storing food and for preparing it. This is a revolutionary technique that has changed the habits of cooks. Vacuum equipment opens up great opportunities for a variety of menus, provides high quality dishes. The use of vacuum technology is one of the main opportunities to improve the level of restaurant service in Russia. ⠀

Передовое кухонное оборудование

Advanced Kitchen Equipment

What kitchen equipment is most suitable for processing “advanced” products? ⠀
⠀
♨ Induction cookers ⠀
⠀
Induction processing of food is based not on the transfer of energy from a heat source, but on the creation of an induced current by an alternating magnetic field in a metal bowl in which food is cooked. Energy is transferred directly to the place where the dishes come in contact with a glass-ceramic stove. The rest of the surface of the plate remains cold. Induction cookers are equipped with an electronic temperature control device (accurate to 1 ° C), which can change almost instantly. ⠀
⠀
💢 microwave ⠀
⠀
Despite the fact that microwave ovens appeared in the 1940s, they can still be considered innovative equipment. There are models of different sizes (with a capacity of up to 35 liters). In the “tunnel” models controlled by a microprocessor with an internal probe, the power supply is cut off as soon as the cooking process is completed. All microwave ovens must be leakproof, protected against electromagnetic radiation. A microwave oven can work like an ordinary electric oven, but it is usually used to restore pre-cooked meals and prepare meals from frozen or vacuum-processed foods. Externally, dishes cooked in a microwave oven are similar to dishes that have been steamed, so the microwave oven is more suitable for food that does not require frying. ⠀
⠀
⭕ Electronic pasta machine ⠀
⠀
This device is very easy to use and guarantees excellent results. It is necessary for restaurants with Italian cuisine and establishments that offer a variety of pasta side dishes. The central cooking container is divided into several sections with folding baskets in which you can set different cooking modes for different types of pasta. Just turn on the timer - and you can engage in other kitchen operations. To maintain such equipment does not require high professional training of personnel. ⠀
