Refrigeration equipment in production is not just a technique for cooling, but a critical element of the technological chain. The quality of products, compliance with sanitary standards, and even the financial stability of the enterprise depend on its proper operation. Unlike household models, industrial refrigerators solve a range of problems: from maintaining the temperature regime for perishable products to ensuring the safety of pharmaceutical products.
In this article we will look at what functions refrigeration equipment performs in production, what types exist and what to look for when choosing. We will pay special attention to regulatory requirements - failure to comply with them can lead to fines, damage to goods, or even production stoppage.
1. The main tasks of refrigerators in production
Industrial refrigerators perform several key functions at once, without which it is impossible to organize efficient production. The main one is extending the shelf life products. For example, meat products at a temperature of +4°C remain fresh for up to 5 days, and at 0°C for up to 10 days. But this is only the tip of the iceberg.
Other important tasks:
- 🔹 Compliance with technological processes. Many products (cheeses, sausages, yoghurts) require strict temperature conditions at the stages of fermentation, ripening or cooling.
- 🔹 Protection against microbiological risks. Low temperatures slow down the growth of bacteria (Salmonella, Listeria, E. coli), which is critical for food and pharmaceutical production.
- 🔹 Ensuring the safety of employees. In the chemical and oil and gas industries, refrigerators are used to store reagents that become explosive when heated.
Without refrigeration equipment it is impossible to meet the requirements GOST R 51705.1-2001 (for food production) or GMP (for pharmaceuticals). Violation of these standards leads to seizure of products and fines of up to 500,000 rubles.
2. Types of industrial refrigerators and their purpose
The choice of refrigeration equipment depends on the specifics of production. For example, it is suitable for a meat processing plant blow freezer, and for a confectionery - display display with adjustable humidity. Let's look at the main types:
| Type of equipment | Temperature conditions | Where used | Features |
|---|---|---|---|
| Blast freezing chambers | from −18°C to −40°C | Meat processing, fishing industry | Freezing to −18°C in 2–4 hours |
| Refrigerated display cases | from +2°C to +8°C | Shops, confectionery shops | Transparent walls for displaying goods |
| Laboratory refrigerators | from +2°C to +10°C | Pharmaceutics, medical laboratories | Precise temperature control (±0.5°C) |
| Modular refrigeration chambers | from −25°C to +10°C | Warehouses, logistics centers | Prefabricated design, scalable volume |
For industries with high hygiene requirements (for example, dairies), refrigerators made of stainless steel AISI 304 with antibacterial coating are used. In pharmaceuticals, models with double cooling system - in case of failure of the main compressor are often used.
3. Regulatory requirements for refrigerators in production
The operation of refrigeration equipment is regulated by a number of documents. The main ones are:
- 📄 SanPiN 2.3.2.1324-03 —hygienic requirements for the shelf life of food products.
- 📄 GOST 31934-2012 —rules for the transportation and storage of perishable products.
- 📄 FZ No. 29 “On the quality and safety of food products” — liability for violation of temperature conditions.
Critical information: according to Resolution of the Government of the Russian Federation No. 1286, maintenance of temperature control logis mandatory in production. Its absence during inspection by Rospotrebnadzor faces a fine of up to 200,000 rubles.
Additional provisions apply for pharmaceutical production rules:
- 💊 Vaccine storage temperature: from +2°C to +8°C (according to Order of the Ministry of Health No. 646n).
- 💊 Humidity control: no more than 60% for most drugs.
- 💊 Mandatory validation of equipment (checking the accuracy of temperature maintenance).
What will happen if you do not comply with the temperature regime?
If the storage conditions are violated, meat products can become a source of botulism or salmonellosis. In pharmaceuticals, improper storage leads to loss of effectiveness of drugs (for example, insulin loses its properties at temperatures above +8°C).
4. How to choose a refrigerator for production: 5 key parameters
When purchasing industrial refrigerator, pay attention to the following characteristics:
- Temperature range. For meat, a mode of up to −18°C is required, for dairy products - +2...+6°C.
- Chamber volume. Calculate based on the daily volume of products + 20% of the reserve.
- Cooling type:
- 🔧 Fan —fast cooling, but high price.
- 🔧 Static —cheaper, but distributes cold more slowly.
For industries with high hygiene requirements (for example, cheese making), choose models with automatic defrosting system (No Frost). This eliminates the formation of ice, which can become a source of bacteria.
☑️ Check before purchasing a refrigerator
5. Typical errors during operation and their consequences
Even the most modern equipment can fail due to improper use. Common mistakes:
- ❄️ Camera overload. It interferes with air circulation and leads to uneven cooling. Consequence: damage to part of the product.
- ❄️ Ignoring defrosting. Ice on the evaporator increases energy consumption by 20–30%.
- ❄️ Lack of sensor calibration. An error of 1–2°C can spoil vaccines or dairy products.
Real case: at one of the meat processing plants in the Moscow region, due to a faulty thermostat, the temperature in the chamber rose to +10°C. As a result, 3 tons of sausage products worth 1.2 million rubles were disposed of.
⚠️ Attention: if your production works with flammable substances (for example, solvents, acetone), use refrigerators with intrinsically safe design (labeling Ex). Conventional models can become a source of fire!
6. Maintenance: how to extend the service life of equipment
The average service life of an industrial refrigerator is 10–15 years, but only with proper care. Main activities:
| Type of maintenance | Frequency | What is checked |
|---|---|---|
| Cleaning the condenser | once every 3 months | Removing dust, checking ventilation |
| Checking freon | once a year | Leaks, system pressure |
| Calibrating sensors | 1 time every 6 months | Accuracy of temperature readings |
| Replacement of seals | once every 2 years | Integrity, elasticity |
For pharmaceutical refrigerators mandatory validation —checking compliance with the declared parameters. It is carried out by specialized laboratories with the issuance of a protocol. The cost of the service is from 15,000 rubles.
Practical example: a freon leak was discovered at an ice cream production plant after scheduled maintenance. Fixing the fault cost 45,000 rubles, but prevented compressor breakdown (replacement cost ~300,000 rubles).
7. Alternatives to traditional refrigerators in production
In some cases, it is advisable to use non-standard solutions:
- ❄️ Cryogenic systems (nitrogen freezers). Used for ultra-fast freezing (up to −60°C in 10 minutes). Suitable for premium products (caviar, deli meat).
- ❄️ Thermoelectric refrigerators. Quiet, but less powerful. Used in laboratories for storing reagents.
- ❄️ Mobile refrigerated containers. Rent costs 5,000–15,000 rubles/month. Convenient for seasonal production (for example, harvesting berries).
For small industries (bakeries, mini-cheese factories) are suitable monoblock refrigerators with a volume of up to 500 liters. Their advantage is ease of installation (they do not require a separate room).
⚠️ Attention: if your production is located in a region with a hot climate (temperatures above +30°C), choose refrigerators with tropical design. Standard models in such conditions overheat and fail 2-3 times faster.
FAQ: Frequently asked questions about refrigerators in production
Is it possible to use a household refrigerator on a small production?
No, this is a violation SanPiN 2.3.2.1324-03. A household refrigerator does not provide uniform cooling and does not have corrosion protection. The exception is temporary storage (no more than 2 hours) in case of emergency.
How often do you need to defrost an industrial refrigerator?
For models without No Frost - 1 time per 2 weeks. For systems with automatic defrosting - as ice forms (usually once every 3-6 months). In pharmaceuticals, defrosting is carried out strictly according to the schedule agreed with Rospotrebnadzor.
What temperature should be in the refrigerator for storing meat?
According to GOST 31778-2012:
- Fresh meat: from 0°C to +4°C (shelf life - up to 5 days).
- Frozen meat: −18°C and below (shelf life - up to 12 months).
What to do if the refrigerator does not hold the temperature?
Urgent measures:
- Check the door seals for integrity.
- Clean the condenser from dust.
- Make sure that products do not block the ventilation grilles.
If the problem persists, call a specialist. Self-repair of refrigeration systems is dangerous (risk of freon leakage).
Is it necessary to register a refrigerator with Rospotrebnadzor?
The refrigerator itself does not need to be registered, but the production must have sanitary and epidemiological report the premises where it is installed. Also required equipment certification (included in the delivery package).
