Reason brine can be placed in advance it is spare in 4 degree of refrigerator-freezers, to reduce the Production Time of slob.
Second step：It takes out ice making basin to carry out disinfection, ice making basin can for example be sterilized by high temperature.
Third walks：A certain amount of refrigerant (for example, 50% alcohol of about 1.2L) is put into cooling bath.
4th step：Sterile ice machine booting, so that refrigerant temperature drops to predetermined temperature (for example, 4 degree).
5th step：Disinfection will be passed through and the ice making basin being cooled to room temperature is put into cooling bath.
6th step：Sterile saline is injected in sterile ice making basin and is cooled down, when ice is initially formed with poly- carbonic acid
Ester shovel stirring is to form required slob.
The preferred embodiment of the utility model has already been described in detail above, it is understood that if desired, embodiment can be changed
Aspect using the aspect, feature and design of various patents, application and publication provide other embodiment.
In view of detailed descriptions above, these and other variation can be made to embodiment.In general, in claim
In, term used should not be construed as limited to specific embodiment disclosed in description and claims, but be understood that
It includes whole equivalency ranges that all possible embodiment is enjoyed together with these claims to be.
