First, function and principle: the vacuum rolls rubs machine is mainly suitable for raw material meats as well as each kind of each kind of livestock, the birds and beasts, fish product and so on steam boiling ham, sausage souse processing. the material meat under the vacuum state, through blade's pump circulation massage, beats, the settlement, the acceleration salt water distribution and the absorption, the promotion muscle fiber protein dissolution and the extraction, improves the product quality, reduces the steam boiling loss. the process rolls rubs the craft, may reduce the salting period, the improvement meat product quality. two, performance characteristics: mostly uses the entire high quality stainless steel manufacture. vertical feeds, the horizontal-type incline rolls rubs, ease of operation. provides the relay automatic timing control installment, realizes the clockwise, the suspension, the reverse, the suspension automatic operation circulation. the fission type pulls out the vacuum system.
