Raw Material Cleaning Equipment
Drum Washer: It is usually composed of a stainless - steel drum, a spraying device, and a drainage system. After the raw cashew nuts enter the drum, with the rotation of the drum, they are rinsed by the sprayed water to remove impurities such as dust and soil on the surface. Its advantages are high cleaning efficiency, the ability to clean cashew nuts evenly, and it will not cause excessive damage to cashew nuts.
Bubble Washer: It uses the bubbles generated by an air compressor to form a large number of bubble streams in the cleaning tank. The cashew nuts are cleaned under the action of the tumbling of the bubbles and the water flow. This equipment can effectively remove the tiny impurities on the surface of cashew nuts. At the same time, it has a certain gentle friction effect on the skin of cashew nuts, which can clean the surface better.
Shelling Equipment
Mechanical Sheller: Generally, it uses the principles of extrusion, shearing, or impact to shell cashew nuts. For example, through two relatively rotating rollers, the cashew nuts are clamped in the middle, and the pressure and friction of the rollers are used to break the cashew nut shells, thus achieving shelling. This equipment has a relatively high shelling efficiency, but there may be a certain rate of broken kernels.
Microwave Shelling Equipment: It uses the thermal effect of microwaves to rapidly heat and vaporize the moisture inside the cashew nuts, generating pressure, which causes the cashew nut shells to break. Microwave shelling has the advantages of high shelling efficiency, little damage to the kernels, hygiene, and environmental friendliness, and can better maintain the quality of cashew nuts.
Peeling Equipment
Steam Peeler: The cashew nuts are placed in a sealed steam chamber, and the cashew nut skins are softened by high - temperature steam. Then, the skins are removed by means of mechanical friction or water flushing. Steam peeling can remove the cashew nut skins relatively cleanly and will not cause too much loss of the nutritional components of the kernels.
Chemical Peeling Equipment: Usually, chemical solutions such as sodium hydroxide are used to soak the cashew nuts, separating the cashew nut skins from the kernels. Then, the skins are removed by methods such as water washing. This method has a good peeling effect, but it is necessary to strictly control the concentration of the chemical solution and the treatment time to ensure food safety and the quality of cashew nuts.
Grading Equipment
Vibrating Screen Grader: It is composed of components such as a vibrating motor and a sieve. The cashew nuts are screened on the vibrating screen through sieve meshes with different apertures, and are divided into different grades according to the size of the cashew nuts. The vibrating screen grader has a simple structure, is easy to operate, and has a relatively high grading efficiency.
Photoelectric Grader: It uses photoelectric sensors to identify and detect the characteristics of cashew nuts such as color, shape, and size. Then, pneumatic or mechanical devices are used to separate cashew nuts of different grades. The photoelectric grader has a high grading accuracy and can effectively remove unqualified products such as discolored grains and broken grains.
Packaging Equipment
Weighing and Packaging Machine: It can achieve accurate weighing and packaging of cashew nuts. Usually, an electronic weighing system is used, which can automatically complete the metering and bagging operations of cashew nuts according to the set weight. Some advanced weighing and packaging machines also have functions such as automatic weight adjustment and elimination of unqualified products.
Vacuum Packaging Machine: The packaging bags containing cashew nuts are placed in a vacuum chamber, and the air is pumped out and sealed to extend the shelf life of cashew nuts. Vacuum packaging can effectively prevent cashew nuts from oxidation, moisture absorption, and pest damage, and maintain the taste and quality of cashew nuts.
