Exhaust casing The steak

Exhaust needle board is mainly used for modulation of steak, steak modulation first wanted to take jin steak, then turn the beef injection liquid seasonings, then after the completion of beef compressed into cylindrical, then pretend to film bag, the beef compression bar into the film bag in this step, be sealed after the beef into thin film bag, but in the film bag saved a large amount of air, the air without treatment can lead to follow-up after frozen steak to produce a large number of holes, currently in the process of exhaust is insufficient, while using exhaust needle plate will air discharge, but basic through pure manual operation to complete this step, not only time-consuming, laborious work efficiency is not high, the low degree of automation. My company developed can not using external equipment for the steak to exhaust, itself is the exhaust products.
