Many people do not understand the importance of boilers to the food processing industry. Boilers can provide hot water, steam, hot oil and other media for food processing, sterilization, insulation and drying. Therefore, boilers are crucial in the food industry, and the performance, efficiency and safety of boilers directly affect the production quality, cost and environmental protection of the food industry.
Let’s learn about the role of boilers in the food industry and practical examples.
The Role of Boilers in Food Production
A boiler is a device that heats water to high temperature and high pressure to produce steam. Steam has many uses in food production, mainly including the following aspects:
1. Steam Generation
Steam is a clean, convenient, and controllable energy source that can be used to drive various food processing equipment, such as mixers, separators, dryers, etc. Steam can also be used to provide hot water for operations such as cleaning, rinsing and disinfection.
2. Heat Transfer
Steam can transfer heat to food raw materials or finished products through heat exchangers or direct contact to achieve heating, boiling, cooking, sterilization and other purposes. The temperature and pressure of steam can be adjusted according to different food characteristics and quality requirements to achieve the best processing results.
3. Sterilization and Pasteurization
Steam can be used to kill microorganisms in food, extend the shelf life of food, and improve food safety. Steam sterilization is a high-temperature and short-time treatment method that can effectively eliminate bacteria, fungi, viruses and other harmful substances while maintaining the nutrition and flavor of food. Pasteurization is a treatment method that uses steam to heat food to a certain temperature and maintain it for a certain period of time. It is often used to sterilize liquid foods such as dairy products and juices.
4. Facility heating
Steam can also be used to provide a constant temperature and humidity environment for food production workshops and create comfortable working conditions. Steam can be passed through radiators or air handling units to distribute heat to various areas to achieve temperature and humidity control. Steam heating systems can also recover waste heat and improve energy utilization.
Real Cases of Boiler Applications
Boiler Project: 2 Set Gas Fired Steam Boiler
Control System: PLC Control
Location: Hebei province,China
Description: Hebei Dongkang Emulsion mainly produces dairy products (milk powder, other dairy products) and edible oil products
In addition to generating hot steam for sanitation and cleaning purposes, steam is also used to heat large ovens or cooking pots. Boilers in food and beverage factories are mainly used for distillation, disinfection, drying, aging and other processes in processing. The product is steamed at high temperatures, dried and sterilized. Therefore, the most used ones are steam boilers. Steam is mainly transported through pipelines, which requires constant steam temperature and pressure. Even the quality of the steam determines the quality of the food shipped out of the factory.
Boiler Project: One Set of 20T/h Gas Fired Steam Boiler
Control System: PLC control+Feedwater frequency conversion control+Fan frequency conversion control
Location: Anhui province,China
Description: Anhui Yingjia Gongjiu Co., Ltd. was listed on the A-share main board of the Shanghai Stock Exchange,which originated in 1955,It manufactures large amount of the white spirit per year to sale the all domestic.
Types of Boilers Used in the Food Industry
In the food industry, boilers are widely used for heating, disinfection, cleaning, etc. According to the direction of water flow in the boiler, boilers can be divided into three types: fire tube boilers, water tube boilers and electric boilers.
fire tube boiler
Fire tube boilers refer to tubes that pass through the water tank in the boiler. The fuel burns in the tubes and transfers heat to the water. The fire tube boiler has a simple structure and low cost, but the steam pressure is low, so it is suitable for small food enterprises.
water tube boiler
A water tube boiler refers to a boiler with water tubes that pass through the combustion chamber. Water flows in the tubes and transfers heat from the combustion chamber to the water tank. Water tube boilers have higher steam pressure and are suitable for large food companies.
electric boiler
Electric boiler refers to a device that uses electrical energy to heat water to boiling and generate steam. Electric boilers are simple to operate and easy to maintain, but their operating costs are high.
In the food industry, boilers are mainly used for the following applications:
Heating: The generated steam or high-temperature water can be used to heat food raw materials, semi-finished products and finished products.
Sterilization: The steam produced by the boiler can be used to sterilize food processing equipment and containers.
Cleaning: The steam produced by the boiler can be used to clean food processing equipment and containers.
Boiler Safety in Food Processing
Boilers are indispensable equipment in food processing and are used for heating, disinfection, cleaning, etc. The safe use of boilers is an important guarantee for ensuring food safety.
Prevent Pollution
Boiler contamination is a major food safety hazard. Boiler pollution mainly comes from the following aspects:
• Boiler water quality: Poor boiler water quality will lead to scaling and corrosion in the boiler, thereby producing pollutants.
• Inside the boiler: Scale, corrosion, and other impurities inside the boiler can also become sources of pollution.
• Boiler Operation: Improper boiler operation can also lead to contamination.
To prevent boiler contamination, the following measures should be taken:
• Use boiler water that meets food safety requirements.
• Regularly inspect the inside of the boiler to remove scale, corrosion and other impurities.
• Operate the boiler strictly in accordance with operating procedures.
Boiler Maintenance
Regular maintenance of the boiler is an important measure to ensure the safe operation of the boiler. Boiler maintenance mainly includes the following contents:
Regularly check the boiler's safety devices to ensure that the boiler is in a safe condition.
Clean the inside of the boiler regularly to prevent scale and corrosion.
Regularly check various performance indicators of the boiler to ensure that the boiler is in good condition.
