DY Heat Recovery Steam Freezer opens up a new road for comprehensive utilization of energy sources.

It is the most sagacious choose for person to select DY Steam Freezer, it only utilizes the surplus steam of the kitchens of hotels, restaurants and enterprises' dining halls.
Range of temperature:	-18, -12, -6, +5°C
Times of heating:	1~2/day, in step with the process of steaming food in kitchen, and 30~40min every time
Requirement for heat:	>0.3~1kg/cm2; COP; 0.3~0.4
Steam pressure:	=>0.5MPa

Unique Superiority:

No electric power but surplus heat is needed, which therefore saves cost of operation. IN accordance with preliminary estimate, compared with refrigerator having the same volume(500L3), every DY refrigerator can save expenditure about 1,500 RMB, hence improves economic performance.
It has no need to use freon, and thereupon protect ozonosphere.
It has no compressor, no motion parts, and little maintenance and repair, as well as there is no need to change the refrigerants. So it has radically solved the most troublesome problem of large amount of maintenance and repair for the kitchen equipment.
Heat Recovery refrigerator can be synchronized with consumption of heat for daily life, which is to say that each day it only needs to be heated once, then a low temperature of 0~-18oC can be kept the whole day. Temperature of the heat is 96~110oC and the heat source for heating may be arranged by the user according to practical conditions. The series products opened up this time mainly utilize saturated steam as the source, it needs only a steam pressure much than or of equal to 0.5 Mpa.
It is with simple structure and of convenience and safety to be operated.
It causes no noise and does not fear of vibration, besides which it also can displace frost automatically.
Time for the return rising of temperature is ten times of over of that of the electrical rise in the refrigerator will not be over the standard value, so the effect of refrigerating and preserving is excellent.

Installation & Utilization:

The surplus heat produced by the heating equipment attached to DY Generator, such as steamer, is used for the attainment of refrigeration and chilling preservation.
Press The evaporate used for chilling preservation can be transported by pipeline, which is only required to be in series-parallel connection with those used for consumption of heat of daily life. Then heating DY Generator to get the effect of chillingervation is accomplished if the switch of evaporates is turned on.
The switch of evaporates can be operated by hand, which is merely required to be turned on once per day, and turned off after 30 minutes.
It can also be installed with automatic switch and operate the whole process above automatically.
It is worthwhile to mention here that at present Pro. Dingyu Li has developed multiple-generators superior to the single generator, which makes the performance of this application more perfect and reasonable.

Specification of Design:
Such application has not been put into mass production yet. But we can design and manufacture various types of DY Steam Freezer with different heat source according to the demands of clients.
