Hot and cold tanks
First, the hot and cold tanks profile
Energy saving, noise reduction, corrosion-resistant, strong production capacity, easy to clean, etc., are widely used in dairy, food, pharmaceutical, chemical, beverage and other industries, as heating, cooling, heat preservation, sterilization or slurry storage must be equipment, ice cream production line necessary equipment. The equipment consists of the liquid storage container, Cycloid reducer, stirring blade and 0oC-100oC thermometer and so on.
 
Second, the hot and cold tanks classification
Press the heating medium can be divided into parts: natural gas hot and cold tanks, steam hot and cold tanks, electric heating hot and cold tanks
Press material can be divided into sub-out: open hot and cold tanks, enclosed hot and cold tanks
According to the structure can be divided into: ordinary type, tapered from top to bottom, the upper and lower head
 
Third, the structure and function of hot and cold tanks
CONSTRUCTION: interior, jacket, insulation layer, the outer foreskin, reducer, stirring paddle, thermometer and so on.
Liner: 304 stainless steel material, surface finish.
Middle Jacket: The A3 steel plate or 1Cr18Ni9Ti made to strengthen the circle spiral devices, cold water from the bottom up (no pressure) to achieve the best lift and cooling purposes.
Insulation Group: the stainless steel plate into a fish-scale pattern made of polyurethane or glass wool insulation with the outside world and maintaining the temperature, heat insulation effect.
Reducer: Cycloid reducer, fixed to the beam of the bracket, wheel speed reducer shaft and impeller connection, the use of loop connection for easy disassembly and cleaning.
Thermometer: Specification 00C ~ 1000C, installed on the beam, minimum for straight medium, the liquid material used in the lowest position can indicate the temperature, to achieve sterilization and aging purposes.
 
Fourth, the installation of hot and cold tanks
 The device feet to adjust the horizontal and vertical reducer up, you can install various pipes, work, pay attention impeller should rotate clockwise, it can not be reversed.
 
Fifth, use and maintenance
1. Description: Before using this equipment shall be cleaned with hot water accumulator light clean, and then steam sterilized. Fixed feed slurry pipe material in the cylinder head into the cylinder, or open into the cylinder head, the material should not be overfilled, so when the material is splashing blender, unsanitary or causing environmental damage.
2, the heating method: heating must be turned off when the refrigerant inlet pipe valve, exhausted remaining refrigerant jacket, and then enter the material, agitator, and then open the steam valve to reach the desired temperature, the steam valve should be closed, over 2 to 3 minutes, then turn off the stirrer.
3, cooling method: Turn off the steam valve, exhausted jacketed remaining steam condensate, and then open the Bottom refrigerant valve, so that the refrigerant from the jacket by lowering the temperature of the cylinder materials.
4, heat: according to the desired temperature, agitator, high-speed valves, and maintaining the temperature (note thermometer) for the purpose of thermal insulation.
5, cleaning: end of the process, after the release of the remaining condensate water to make the cylinder jacket, should rinse with warm water as soon as possible, brush off the slimy material, and then 40C ~ 50C alkaline thorough cleansing of the inner wall of the container, and rinse with water until next time you use with hot water or steam (90C) or more, for 2 to 3 minutes for disinfection.
6. maintenance: the entire equipment should always pay attention to the work and reducer, shall immediately supplement inadequate reducer lubricants, oil change once half (40 # oil), when the device is not in use, be sure to use warm water jacket to avoid salt corrosion, often scrub the cylinder to keep the look clean, bright interior, to achieve durable purpose.
