Today, let's introduce the heating method of electric heating mixing tank
Liquid mixing tanks are mainly used in industries such as food, daily chemical, and petroleum, such as coatings, pigments, laundry detergent, detergent, shower gel, glue, resin, etc. They are containers for completing hydrolysis, neutralization, crystallization, evaporation, mixing, and other process processes. They can also be equipped with heating devices, insulation devices, and cooling devices according to customer process requirements.
Heating mixing tank is a highly versatile equipment. In the food and beverage industry, it is used for mixing, blending, sterilization, and insulation of dairy products, juices, and seasonings; In the chemical and daily chemical industries, it is used for mixing and reacting raw materials for coatings, resins, and cosmetics. When selecting, it is necessary to comprehensively consider factors such as material characteristics, process temperature and time, hygiene level, production scale (volume ranging from 10L to 5000L), and available heat sources.
There are various heating methods for heating mixing tanks, mainly including steam heating, electric heating, and circulating heating of media such as thermal oil.
According to the different heat sources and structures, there are several types of heating mixing tanks, each with its own advantages and disadvantages:
Electric heating mixing tank: using electric energy as the main heat source, environmentally friendly, safe, and easy to install, but the heating speed may be slower than steam heating, and the energy consumption is relatively high.
Steam heated mixing tank: using steam to heat through a jacket, with fast heating speed and high cleanliness, especially suitable for hygiene grade production such as food, but requires a supporting boiler and a large initial investment.
Coil heating mixing tank: Install coils inside the tank or use semi-circular coils externally, with steam or heat transfer oil flowing through the tubes. The inner coil tube has fast heat exchange and uniform heating, but it will occupy space inside the tank and is inconvenient to clean; The outer half tube does not occupy the volume inside the tank and has good pressure resistance, but it requires high welding requirements.
Steam direct heating: Steam is directly introduced into the mixing tank and comes into contact with the material for heating. This method heats up very quickly, but it is important to control the pressure and temperature of the steam to avoid any adverse effects on the material.
Electric heating is a widely used heating method, mainly in the following forms:
Electric heating tube heating: Install electric heating tubes inside the jacket of the mixing tank, heat the thermal oil or water inside the jacket through thermal conduction, and then heat the material through the circulation of the medium. You can also directly insert the electric heating rod into the jacket for heating.
Coil heating: Install heating coils inside or outside the tank to provide heat through the circulation of heat medium. This method provides more complete contact with the material, but the diameter of the mixing tank cannot be too large, making it more suitable for small mixing tanks.
