Hot and cold cylinder overview
Cold and hot cylinders (also known as aging cylinders) can be used as cleaning tanks, mixing tanks, temporary storage tanks, batching tanks, etc., which have the advantages of energy saving, noise reduction, corrosion resistance, strong production capacity and convenient cleaning. In the dairy industry, food, pharmaceutical, chemical, beverage and other industrial sectors, as a necessary equipment for heating, cooling, heat preservation, sterilization or storage of slurry, hot and cold cylinders are especially suitable for pasteurization and insulation of milk, which is necessary in ice cream production line. equipment.
First, the classification of hot and cold cylinders
According to the heating medium, it can be divided into: steam cold and hot cylinder, electric heating cold and hot cylinder;
According to the material in and out, it can be divided into: open type hot and cold cylinder, closed type hot and cold cylinder;
According to the structure, it can be divided into: ordinary type, upper and lower cone, upper and lower head;
Second, the structure and function of the hot and cold cylinder:
Structure: It consists of inner liner, jacket, insulation layer, outer sheath, reducer, stirring paddle, thermometer and so on.
1. Liner: Made of stainless steel 304 material with polished surface.
2. Middle jacket: It is made of A3 steel plate or 1Cr18Ni9Ti steel plate. The spiral coil device is reinforced, and the cold water is from bottom to top (no pressure) to achieve the best lifting and cooling.
3. Insulation group: It is made of stainless steel plate and thrown into a fish scale pattern. The insulation layer uses polyurethane or rock wool to maintain the temperature with the outside world to achieve the effect of heat preservation.
4. Reducer: Cycloidal pinwheel planetary reducer is fixed on the bracket in the beam. The reducer wheel output shaft is connected with the stirring paddle. It is connected by a looper for easy disassembly and cleaning.
5, thermometer: specifications 0 ° C ~ 100 ° C, the installation of the beam, straight extension of the minimum media position, so that the liquid material used to the lowest position can also indicate the temperature, to achieve sterilization and aging purposes.
Third, the installation of hot and cold cylinders:
Adjust the feet of the equipment until the horizontal line is perpendicular to the reducer to install the pipes. When working, be careful that the paddles should rotate clockwise and must not be reversed.
Fourth, the use and maintenance of hot and cold cylinders:
1. Description: Before using the Klau brand hot and cold tank, the liquid reservoir should be cleaned with fresh water and then steamed. The material slurry enters the cylinder from the material pipe fixed on the cylinder head, or the cylinder head is opened, and the material should not be packed too full, so as to prevent the material from being splashed when stirred by the agitator, resulting in unsanitary or loss of environment.
2. Heating method: When heating, the condensing inlet port must be closed, the remaining condensation in the jacket should be exhausted, then the material should be input, the stirrer should be turned on, and then the steam port should be opened. After reaching the required temperature, the steam port should be closed first. After ~3 minutes, turn off the stirrer again.
3. Cooling method: close the steam port, release the remaining steam condensate from the jacket, and then open the bottom condensing port to make the condensation pass through the jacket to reduce the temperature of the material in the cylinder.
4. Insulation: According to the required temperature, start the stirrer, switch at high speed, and keep the temperature (pay attention to the temperature gauge) in order to achieve the purpose of heat preservation.
5. Cleaning: After the processing is finished, after draining the remaining condensed water in the cylinder, it should be rinsed with warm water as soon as possible, brush off the sticky materials, then thoroughly clean the inner wall of the container with 40~50 °C alkaline water, and rinse with water. For the next use, use hot water or steam (90 ° C) or more to maintain disinfection for 2 to 3 minutes.
6. Maintenance: Always pay attention to the working condition of the whole set of equipment and reducer. When the reducer oil is insufficient, it should be replenished immediately. Change the oil once every half year (40# oil). When the equipment is not in use, be sure to rinse the jacket with warm water to avoid Corrosion of salt water, often scrubbing the cylinder to keep the appearance clean and the inner liner bright for durability.
