Functions and working principle: RGR-250VT vacuum tumbler is mainly used for cooking hams, sausages and other raw meat, as well as used in preserving process of all kinds of livestock, poultry and fish. Under vacuum condition, raw meat will be kneaded, threshed and held by rotating paddle, and that will accelerate the brine infiltration and dissolving and extraction of parapeptone. Through this method, the product ratio will be improved and cooking loss is reduced. By tumbling, the time of preserving process will be shortened and meat quality is improved.Functional characteristics: 1) Fully constructed by high quality stainless steel 2) Vertical feeding, horizontal tilt tumbling, easy to operate 3) Equipped with time relay to control the circulation of forward rotation, pause,reverse rotation and pause automatically 4) Independent vacuum pumping systemMain data: 1) Driving power of drum: 0.75kW 2) Drum capacity: 250L 3) Vacuum pump power: 0.75kW 4) Max. loading: 160kg 5) Vacuum: 0.08MPa 6) Adjustable range of time controller: 3 min - 30 hours 7) Weight: 250kg 8) Drum speed: 11rpm 9) Power supply: 3φ/380V/50Hz, adjustable according to requirement
