A pine nut automatic extrusion opening machine

Abstract

The invention relates to a pine nut automatic extruding opening machine, and belongs to the field of nut opening. The pine nut automatic extruding opening machine includes a support frame, a conveying belt, pine nut cases, an extruding device, an extruding support, a screw, a stepping motor support disc, a first stepping motor, a vibrator, a pine nut box, a back support frame, a baffle plate, drive wheels, seal side plates, a seal ring, a hydraulic oil pipe, a seal connector, and a second stepping motor. The pine nut automatic extruding opening machine is characterized in that the conveying belt is arranged on the support frame through the two driving wheels; the pine nut cases are evenly arranged on the conveying belt; the extruding device is arranged above the pine nut cases; the extruding support is arranged on two sides of the conveying belt; the first stepping motor is arranged on the extruding support through the stepping motor support disc; the upper end of the screw is connected to an output shaft of the first stepping motor; the vibrator is arranged on a side plate of the pine nut box; and the pine nut box and the baffle plate are arranged on the back support frame. The pine nut automatic extruding opening machine can automatically open large and small pine nuts, can reduce labor cost, and can improve the processing efficiency and the opening effect.

Description

technical field [0001] The invention relates to a pine nut automatic extrusion opening machine, specifically, a belt drive and a hydraulic fixing device are adopted. After the pine nuts are fixed, an extrusion rod is used to squeeze the pine nuts into the opening. Belongs to the field of nut opening. Background technique [0002] Pine nut is a kind of pine fruit rich in oil. The roasted pine nut has a delicate fragrance and is one of the nut foods that people love. But because the shell of pine nuts is very hard, it affects eating. Generally, before roasting, a small opening needs to be made at the top of the pine nuts, so that the shells can be peeled off when eating. At present, there are two methods of opening pine nuts: manual use of opening pliers, which has a good opening effect, but the efficiency is low; one is to use chemical substances to open the opening, soak the pine nuts in chemical reagents such as sodium metabisulfite, soda ash, etc. to brighten the appearan...

Problems solved by technology

However, because the outer shell of pine nuts is very hard, which affects eating, it is generally necessary to open a small opening on the top of the pine nuts before roasting, so that the outer shell can be peeled off when eating.

At present, there are two methods of opening pine nuts: manual use of opening pliers, which has a good opening effect, but the efficiency is low; one is to use chemical substances to open the opening, soak the pine nuts in chemical reagents such as sodium metabisulfite, soda ash, etc. to brighten the appearance of the pine nuts, and then add Talc powder, after more than ten minutes of frying, the pine nuts will crack. This method is efficient, but there will be chemical residues in the pine nuts, which will affect your health; one is to use high temperature and high pressure to open the opening, and use the instantaneous pressure difference to complete the opening. The pine nuts have a good taste, but the skin of the pine nuts turns black after high temperature treatment, and the nutrients are lost after high temperature. At the same time, this high-pressure equipment has certain dangers.
