Regulation of the Minister of Internal Affairs and Administration of June 7, 2010 on fire protection of buildings, other structures and areas Chapter 7 Installations and technical devices § 34. 1. In facilities or parts thereof where the combustion of solid, liquid or gaseous fuels takes place, pollutants are removed from smoke and exhaust pipes during the periods of their use:

1) from furnaces in mass catering establishments and catering services – at least once a month, unless local regulations provide otherwise;
2) solid fuel-fired furnaces not listed in point 1 – at least once every 3 months;
3) from furnaces fired with liquid and gaseous fuels not listed in point 1 – at least once every 6 months.
2. In the facilities or parts thereof referred to in par. 1, remove contamination from the ventilation ducts at least once a year, if the greater frequency does not result from the conditions of use. 3. The activities referred to in para. 1 and 2, are performed by persons with chimney sweeping qualifications.
As it results from the above-mentioned regulations, the person responsible for regular cleaning of ventilation ducts in restaurants is a chimney sweep.
Due to the fact that it is a specific type of cleaning, this type of work should be carried out by chimney sweepers with appropriate knowledge and training, and having professional tools.

How often these cleanings are performed depends on how quickly a layer of grease builds up in the exhaust system. In the normal operation of the restaurant, such cleaning often needs to be carried out quarterly, or even more often. Failure to clean the exhaust ventilation and the gastronomy hood from the remaining fat may lead to spontaneous combustion of the ventilation and fire in the building.

What is cleaning ventilation in restaurants? (Restaurant Hood Cleaning Warsaw, Kitchen exhaust cleaning Warsaw) How do we remove contaminants from the hood and in the exhaust ducts to which the gastronomic hood is connected?

The hood in a restaurant kitchen is usually made of stainless steel. Its task is to collect steam and smoke resulting from cooking, frying, baking etc. At the entrance to the exhaust ventilation duct there are filters, often along the entire length of the hood. Filters catch grease particles from the hot steam flowing through them. In this way, part of the fat precipitates on the walls of the hood and on the metal filters. Further, the hot air along with the remaining fat content travels through the ventilation ducts as far as the fan. The fan is usually located on the roof of the building.

Sometimes it is the fan that gets so much fat in the kitchen when cooking food that it forms a film that blocks it and holds it in place. This is often the moment when kitchen users ask us to clean the restaurant’s exhaust system.
The grease in the ventilation duct is removed with special chemicals, which are applied with an active foam generator. Often, cleaning of such greasy eaves canal must also be performed with rotating brushes driven by a screwdriver. The special design of the cleaning heads scrapes grease and baked proteins from the walls of the ventilation ducts.

The most popular and most effective method of removing fatty deposits from ventilation ducts in restaurants is cleaning with active foam (wet), assisted by mechanical cleaning with rotary cleaning sets.

Do I need to clean the exhaust ducts and the hood of the catering kitchen?

Yes. As in other types of restaurant kitchens, in the kitchen where the food processing process for catering purposes takes place, equipped with a gastronomic hood, it is necessary to regularly clean the exhaust ventilation, exhaust fan and clean the hood.

How to improve the draft in the cooker hood in a restaurant kitchen? Why is the ventilation draft in the kitchen weak – how to strengthen it?

One of the reasons for the poor draft of exhaust ventilation in a restaurant kitchen is a greasy and heavily soiled exhaust fan. In order for the fan to efficiently and effectively extract and discharge kitchen fumes outside, it must be clean. If the exhaust fan is not cleaned regularly, a thick layer of fat and baked proteins will accumulate on its blades. Such a dirty fan has a very reduced efficiency of extracting fumes, its power drops drastically. In order for the exhaust fan in the restaurant to have the required capacity, it must be cleaned regularly, as well as other elements of the exhaust system in the kitchen. It is equally important to regularly clean the hood, grease filters and technological ventilation ducts through which greasy air is blown from the kitchen.

Smells from the restaurant kitchen reach the consumption room, how to prevent this?

The reason is in most cases an improperly designed ventilation system in the catering establishment. Often the cause of frying or cooking odors from the kitchen to the consumption room is also blocked or heavily contaminated exhaust ventilation. If there is ventilation in a restaurant or bar and it is not cleaned regularly, it is probably dirty. The grease on the walls of the exhaust ducts and other by-substances precipitated from kitchen vapors effectively weaken and block the proper flow in the exhaust ventilation ducts. The weakened draft in these pipes means that some of the air from the kitchen, unable to escape naturally through the hood, wanders around the entire premises, also around the consumption room. Such unpleasant smells of frying or cooking can effectively deter customers from revisiting restaurants.
