May phan loai dieu tho 1024x768 Cashew nut processing technology

cashew calibrating machine

Application: Cashew cleaning and sorting machine use for cleaning cashew and categories whole kind size as A, B, C, D …

Feature:

  • In this process we separate different sizes of cashew nuts with the help of a electric calibrator. This calibrator has holes of different dimensions, starts from 18mm, separate five grades. Grading of nuts normally used for mechanical plants to facilitate in assures even drying in Dryer treatment, making shelling it can be avoided, worker always wants to cut big nuts, labor turnover.
  • Fully automatic system that reduces labour in comparison with the solutions available on the market and helps the operation control by advanced electronic control system
  • More uniform and precise calibration granted by the different processing concept and the adopted manufacturing solutions.
  • More safety for the plant users and respect to the processing: utmost protection and least down time periods.
  • Less space requirement in comparison with same capacity.
  • Less energy consumption in comparison with same capacity.
  • Low maintenance costs.

FULL AUTOMATIC CASHEW SHELLING SYSTEM

shelling line Cashew nut processing technology

Automatic cashew shelling line,cashew shelling machine,cashew shelling machinery

Application: cashew kernel humidificating machine cutting to take cashew kernel

Feature:

  • The objective of shelling is to produce clean, whole kernels free of cracks.
  • The steam cooked & air cured nuts are de-shelled by hand and leg operated cutters, and now a day’s some semiautomatic and fully automatic machines are arrived in market for fast process. Pair of workers are needed for one cutter. While the cutter de-shells the nuts, the other worker retrieves the kernels from the shell. The nuts are fed one by one manually between the two sets of blades to fit the contour of the fixed blades. The pressing of the pedal pierces the nut on the convex side by means of two blades. The two blades are used to splits the nut by operating the handle of the cutter. After de-shelling, the nut falls freely due to gravity and is collected beneath the cutter.
  • This section is the key of success of the production. A pair of workers can cut near about 75 to 80 kgs of the nuts in normal conditions (when the quality of the nuts is of the superior grades). In many places people don’t like to work in groups there they can work alone with one cutter cutting as well as separating the shell and kernel at the same time, this system will allow you to check the broken at any stage of shelling.
  • In semi automatic shelling process one worker can handle 10 stations. Hi has to feed the RCN in shelling machines hopper at regular interval. Semi automatic shelling machines capacity depends upon the size of the RCN. Depending upon the variety of semi automatic shelling machine single station can handle 60-65 nuts per min in most of the Indian made machines, you can say about 70% of the market. Some machines are also available with capacity of 130-140 raw cashew nut per min capacities. In the starting these machine gives best result but when the time passes performance goes down. first 6 month these machines gives 85-95% Shelling, broken ratio is 4-7%. But after six month unshelled ratio goes to 30-40% while broken ratio also goes too high.
  • Now we are going to use a third version of our machine which has best stability with time. Capacity of the machine is 260-300 Raw Cashew Nuts per min.

Specification of Automatic cashew shelling line new version (with 6 shelling machine) and 6 knife/machine)

  • Capacity: 3800 – 4800 kg/8 hour
  • Capacity: 480 – 600  kg/hour
  • Total power: 18 HP
  • White whole ratio : 80-95 %
  • Broken ratio : 5 – 10 %
  • Dimension (LxRxH): 10,000 x 9,000 x 3500 mm
