When the material passes through this gap, the speed of material that is attached to the rotor surface is the largest due to the high speed rotation of the rotor, but the velocity of material attached to the stator is zero, which results in a sharp velocity gradient. Thus, the material is subjected to strong shear, friction and turbulence, and the effect of ultrafine micro comminution is produced.

4. Cocoa oil press machine: The main parts of hydraulic oil press machine are hydraulic cylinder, column, beam and activities base, oil pump, cylinder, electric heating coil and automatic temperature control device etc.. The machine is made of high quality metal materials, thus improving the performance of the machine and ensuring the service life of the components.

Theconsists of cocoa roasting machine, cocoa peeling machine, cocoa bean grinding machine, cocoa oil press machine, oil cake cruching machine and cocoa powder making machine. It can produce deep, vividly coloured cocoa powder. These machines are an ideal machinery for cocoa powder processing plant.Main Machines Introduction:1.It uses electric heating type or fuel oil, gas or coal as heat source, adopts rotary drum, heat conduction and heat radiation principle, and low production cost (when baking, cocoa bean do not contact with pyrotechnics). The roaster has been proved by many cocoa bean products factory, which has the advantages of convenient use, high efficiency, energy saving and durable.2.The peeler is a special equipment for crushing and peeling cocoa beans, it adopts spiral roller food grade, has a high degree of automation, valve broken rate is high, low noise, no pollution etc.. The peeling machine has suction device and vibrating screen. The vacuum cleaner can suck the skin of cacao. Less consumption, so it is the ideal choice for food processing industry.3.The mill is composed of a fixed grinding body (stator) and a high-speed rotating grinding body (rotor). There is a small gap between the two grinding discs.5.: This series of crusher divided into common type and stainless steel. It can crush the cocoa oil cake, chicken skeleton, duck bone, bone and other bones and it is a processing equipment for pre operation do bone paste. The crushing machine has the advantages of large power, good crushing effect, large yield, simple operation, convenient cleaning, safety and reliability, and is a practical device for meat processing plants, slaughtering plants and food distribution centers.6.: This machine is suitable for small scale production and experiment in pharmaceutical, chemical, food, agriculture and foodstuff industries, especially suitable for crushing and drying brittle materials. The machine is simple in structure, stable in operation, low in noise and good in crushing effect.
