Cold ammonia change fluorine

Our main production freeze dryers, vacuum freeze-drying machine enrichment series, spray dryer, microwave dryer, microwave sterilization machine, vacuum frying machine, vacuum impregnation machine, heat exchangers, cold transformation, vacuum drying oven, vacuum oven, etc., has a complete and scientific quality management system. The company's existing freeze dryers can be freeze-dried materials and processing all types, do lyophilized experiment, there is a demand, please call. China's current large-scale food cold, much ammonia as a refrigerant, ammonia is toxic, and is able to fire and explosion in the temperature of the refrigerant in the refrigerator repairs or transformation process as soon as a fire or ammonia leakage accident occurs, to field personnel or the public bring serious harm, or cause significant damage to property, causing serious pollution to the environment. National Standard GB18218-2000 of "major hazard identification" in the ammonia as dangerous substances, and provides critical mass. That is, a cold storage unit, the total amount of ammonia in ammonia refrigeration systems is equal to or exceeds 40T when the unit as a major hazard; Since 1968, there have been the emergence of ammonia gas leak and explosion occurred systems of event, causing serious harm to all site personnel and public property and life, according to this phenomenon, from the requirement to use a security perspective as well as special equipment safety supervision regulations for these uses ammonia as a refrigerant freezers comprehensive reform imperative, I Division after careful research, has developed a system will be transformed into a freon indirect ammonia refrigeration cooling system program and there are many success stories in the country, which will become a major cold storage and cold chain business The best choice! The main library is original ammonia refrigeration system transformation, ammonia chiller and refrigeration system transformation, the original cold storage and refrigeration evaporator drain tube station can be adjusted to retain all; you save a lot of costs, while providing a safe refrigeration system security; new fluorine system before running the original equipment may not move, just opening the access fluorine system on the line. I mainly ammonia library renovation program has two kinds: the first one: the original ammonia refrigeration system into a flooded for fluorine refrigerant liquid glycol systems; to retain the original interior heat exchanger, such as library ceiling pipes, frozen shelf , air coolers, ice-making system in the evaporator coil heat exchanger tube evaporator equipment, but will be replaced with a chiller device company dedicated refrigeration unit; manufactured cryogenic coolants were delivered to the indoor heat exchanger, so as to achieve the set temperature. Has a simple construction, into a cycle is short, easy piping, and low cost. Temperature range can be carried out at + 15 ℃ to -70 ℃. The second: The original ammonia refrigeration system into fluorine bucket pump for liquid cooling systems; suitable for all types of spiral freezer, tunnel IQF machine, air-cooled quick-freezing refrigeration system, or the original cold ammonia discharge pipe replacement a fluorine-discharging pipe system, after the transformation of the refrigeration system with high energy efficiency, system stability, easy management features; freon refrigeration system compared to indirect ammonia refrigeration system has the following Advantages: 1, stable and reliable, long life: the use of chillers Three imported semi-hermetic screw compressors with economizer operation; independent, mutual non-interference; during the initial cooling, three units of work, usually automatically adjust the operating units according to the load demand, providing a spare unit, ensure the stability of the cold storage operation, equipment design life of more than 15 years; 2, simple and safe: the use of R22, R404A, R23 and other fluorine-cold refrigeration, there is no proof the problem, and indirect cooling through glycol secondary refrigerant, which is ordinary water pipes system, the system is simple; 3, low failure rate, maintenance costs province: the refrigerating medium indirect cooling, there is no direct evaporation system back to the oil difficult, refrigerant prone to leaks, leak detection difficult, uneven liquid separation problems; only the need to do regular maintenance to chiller, low failure rate, maintenance costs province. 4, energy efficient: the device can achieve 10% to 100% according to the actual load of cold energy regulation, but by freezing pump for liquid, there is no pressure loss, loss of cold, difficult to control parameters such issues; its controllable; it Integrated high energy efficiency. 5, management is simple, convenient: The system uses Siemens SIEMENS PLC programmable controller full control, can achieve a variety of equipment protection, data display and real-time monitoring; chiller has been factory after factory qualified to run the debugger as a whole, the system is reliable stable, no staff on duty, integrity, strength and quality of products Rizhao City Kai-liang Food Equipment Co., recognized by the industry, worthy of your trust.
