Industrial Automatic Fruit Vegetables Beans Meat Blanching Machine
一. Structure and material
1. Pot structure
The pot body of the industrial blanching machine is generally cylindrical or square, made of corrosion-resistant materials such as stainless steel. This material can not only withstand high temperature and high pressure, but also prevent the corrosion of the pot body by the marinade, ensuring the service life of the equipment.
There are two types of pot bodies, with stirring device and without stirring device. The stirring device can ensure that the materials can be heated evenly during the blanching process and improve the blanching effect. The stirring device can be paddle type, spiral type or other forms. Choose according to different materials and process requirements.
The outside of the pot body is equipped with an insulation layer to reduce heat loss and improve energy utilization efficiency. The insulation layer can be made of materials such as rock wool and aluminum silicate, which have good thermal insulation performance.
2. Heating system
The heating methods of industrial blanching machine mainly include steam heating, electric heating, gas heating and thermal oil heating. Steam heating is heating by passing steam into the inter layer or coil of the pot body and using the heat of steam. This heating method has the advantages of uniform temperature and convenient control, but it needs to be equipped with equipment such as steam generators.
Electric heating is heating by installing electric heating elements at the bottom or around the pot body and converting electrical energy into thermal energy. Electric heating has the advantages of fast heating, clean and pollution-free, but it consumes a lot of electricity.
Gas heating is heating by burning gas to generate heat. This heating method has the advantages of fast heating speed and low cost, but it needs to pay attention to safety issues to prevent accidents such as gas leakage and explosion.
Thermal oil heating is widely used in industrial production. The system consists of a heating furnace, a circulating pump, an expansion tank and heat-using equipment. The heating furnace generates heat by burning fuel or electric heating to heat up the thermal oil. The high-temperature thermal oil is sent to the heat-using equipment under the action of the circulating pump and transfers heat through heat exchange. After the heat transfer is completed, the thermal oil with a lower temperature flows back to the heating furnace for reheating, and the cycle continues. The expansion tank provides space for the volume change of the heat transfer oil, and can also exhaust and replenish the heat transfer oil. The heat transfer oil has low vapor pressure and high boiling point, can stably absorb and transfer a large amount of heat, and achieve efficient and stable heating effect.
3. Control system
Industrial blanching machine are usually equipped with advanced control systems, which can realize precise control of parameters such as temperature, time, stirring speed, etc. The control system can use PLC (programmable logic controller), touch screen and other equipment, which is easy to operate and highly reliable.
The control system can also set an alarm function. When the equipment fails or an abnormal situation occurs, it can issue an alarm in time to remind the operator to deal with it to ensure production safety.
二. Working principle
1. blanching process
Put the materials to be blanching into the industrial blanching machine and add appropriate amount of blanching sauce and seasoning. According to the properties of the materials and process requirements, set the parameters such as blanching temperature, time and stirring speed.
Start the heating system to heat the pot to the set temperature. During the heating process, the stirring device continuously stirs the materials to make the materials evenly heated, and at the same time promotes full contact between the blanching sauce and the materials to improve the blanching effect.
When the blanching time reaches the set value, stop heating, take the material out of the pot, and carry out subsequent processing or packaging.
2. Temperature control principle
The temperature control of the industrial blanching machine is to monitor the temperature inside the pot in real time through the temperature sensor, and transmit the temperature signal to the control system. The control system automatically adjusts the heating power or steam flow according to the difference between the set temperature value and the actual temperature value to keep the temperature inside the pot within the set range.
The temperature sensor can be a thermocouple, thermal resistor and other types, which have the advantages of high measurement accuracy and fast response speed. The control system can use PID (proportional-integral-differential) control algorithm, which can achieve precise temperature control and improve the quality stability of stewed products.
三. Application field
1. Food processing industry
In the food processing industry, industrial blanching machine are widely used in the blanching of meat, bean products, vegetables and other foods. For example, it can be used to make stewed meat, stewed eggs, stewed tofu, stewed vegetables and other products. Industrial blanching machine can improve the taste and quality of food, extend the shelf life of food, and meet consumers' demand for delicious and healthy food.
2.Pharmaceutical industry
In the pharmaceutical industry, industrial blanching machine can be used for heating treatment and extraction of Chinese medicinal materials. By controlling the temperature and time of braising, the effective ingredients in Chinese medicinal materials can be effectively extracted, and the quality and efficacy of medicines can be improved.
3.Chemical industry
In the chemical industry, industrial blanching machine can be used for heating reaction and dissolution of chemical raw materials. For example, it can be used in the production process of synthetic resins, plastics, rubber and other products. Industrial blanching machine can provide a stable heating environment, promote chemical reactions, and improve the production efficiency and quality of chemical products.
In short, industrial blanching machine are an efficient, energy-saving, hygienic and safe blanching processing equipment with broad application prospects. With the continuous advancement of science and technology and the continuous development of industrial production, the performance and functions of industrial blanching machine will continue to improve, providing more powerful support for the development of various industries.
