Continuous autoclave
Technical field
The present invention relates to a kind of sterilization still that food sterilization is handled that is used for, relate in particular to a kind of continuous autoclave.
Background technology
Present China food service industry, to food, especially packaged food generally adopts secondary high temperature sterilization equipment discontinuity will be loaded and unloaded in the sterilization still by disinfecting food in batches, by high-temperature-hot-water or steam food is carried out sterilization processing.
But the sterilization still of existing this class discontinuity sterilization in batches, each sterilization could begin sterilization after must waiting until and all filling the sterilization still.There is following defective in the sterilization still of this structure: food carries out one by one in the production of can or packaging process, the sterilization still then is a collection of product to be carried out sterilization, first product and last product of producing at packaging process in the product of every batch of sterilization have certain time interval always, the product of at first packing out in every batch wait for last product during in, wherein the bacterium in the material can continue breeding unavoidably, this has brought higher requirement just for the follow-up sterilization process and the temperature environment in workshop, and the sterilization intensity of entire block all will be strengthened.Because the increasing of sterilization intensity, the time lengthening that needs product to stop under hot environment makes the high temperature destruction strengthen, thereby has reduced the integrated quality (high temperature will cause the decline of product Natural color, perfume (or spice), flavor quality) of product.Therefore, optimal mode is exactly just to send into be rapidly heated in the tank body sterilization and cooling cooling processing immediately after the packing of product finishes, before sterilization, make the bacterium original amount in the material be in alap quantity levels, and avoid the material secondary pollution after the sterilization.
Summary of the invention
