Autoclave is widely used for food sterilization in glass bottles, plastic bottles, cooking bags, cans such as dairy products, beverage, canned food, rice pudding, ham, meat etc.

According to the various points of view there are so many classification ways of autoclave, so to choose which type has become clients' distress, so our company offers you some about the autoclave selection considerations.

If request for heat distribution is very uniform, you should try to choose the computer automatic autoclave. Computer semi-automatic autoclave's temperature control and pressure control is the same with automatic autoclave, but the price is 1/3 of automatic autoclave.

    Generally you can choose electric semi-automatic autoclave. Manual autoclave sterilization is high difficulty, because controlled temperature and pressure and so on all need artificial to complete, the appearance it is difficult to grasp, tank inflation (bag) and the high broken rate.

a.       If the product is gas packaging or product appearance is stricter, then choose water bath autoclave or spray type autoclave.

b.       If the product is cooking bags, glass bottles/cans packaging, to prevent breakage or jump cover, generally under the pressure sterilization conditions, then should choose the sterilization temperature and pressure control of sterilization equipment, respectively, such as spray autoclave, water bath autoclave or steam autoclave.

Glass bottles, cans, steam and cooking packaged food sterilization examples show

c.       Product packaging size or weight is larger, heat transfer speed slower flexible packing products, then choose all water autoclave, this autoclave also called water bath autoclave, such as the net weight above 500g, Solids content in more than 70% of the class soft canned paste body. Such as the large pieces of duck, chicken, fish blocks, such as Beijing roast duck.

d.       Product heat sensitive to higher demand, the consistency or sterilization is higher, then choose the rotate autoclave, such as high rice pudding (cans), But now our cup congee should choose steam autoclave or water bath autoclave, mainly considering due to heat sterilization process, the soft cup deformation, looks ugly, not easy to sell

e.       Tin cans, can adapt to a certain pressure difference and temperature difference is not easy to deformation, so can choose the steam sterilization or spray sterilization, but do not generally choose bath type autoclave.

f.        The lid of the bottle is mostly easy open lid, when sterilization (insulating section) the pressure in the bottle is higher than external pressure. If the steam sterilization, it cannot add back pressure, causing jump cover, so the steam sterilization method is not suitable for glass bottle. Generally we choose spray type autoclave and generally with plate heat exchanger cooling, it's mainly to prevent glass sharp cooling in the process of cooling and burst.

g.       Vacuum soft packaging under the pure steam will produce yield up bag phenomenon; artificially high pressure sterilization will avoid raising bag, but at the same time will cause the kettle uneven distribution of internal heat, sterilization is not complete, so the steam type sterilization pot is not suitable for vacuum soft packaging. Generally choose spray autoclave or water bath autoclave.

h.       Ham sausage foods, similar with vacuum soft packaging, and combined with the contractile properties of nylon casing at high temperature, must be uniform around the casing and heat, The contraction can even, if uneven contraction the ham sausage will become bent after sterilization. So are suitable for water immersion sterilization kettle.

i.         Boxed products, as long as it doesn't because of excessive packaging, and produce obvious heated surface of yin-yang and color distortion. Some packing weight is very big, but the packaging was thin and won't produce the heated surface of Yin-Yang. Spray type sterilization kettle is suitable for vacuum soft packaging sterilization.
