Description

Chinese torreya peeling separator Technical Field The invention belongs to the technical field of agricultural product processing, and particularly relates to a torreya peeling separator. Background Chinese torreya is taken as a special rare dried fruit in China, the edible part of Chinese torreya is hard kernel, and the meat-like epicarp which is difficult to remove is wrapped outside the Chinese torreya. The collected torreya is subjected to multiple procedures such as peeling, cleaning, airing and the like, wherein peeling is a key link affecting the efficiency and the quality of a finished product. Traditional manual peeling is extremely low in efficiency, and torreya grandis peel contains resin with strong irritation and adhesiveness, and is easy to damage hand skin, so that mechanical peeling has become a necessary requirement for industrial development. Currently, common mechanical peeling schemes rely mainly on the principles of mechanical rolling and friction. A typical apparatus includes a hopper disposed on a frame, one or more pairs of oppositely rotating grinding drums, and a screening or drum type separating device for separating the peel from the pit. During operation, the torreya fruits fall into the gap between the rolling rollers from the feed hopper, and the epicarp is broken and loosened through the extrusion and kneading actions of the rollers. The mixture then falls into a separation mechanism which sorts the kernels and the crushed pericarps to different collection ports by their difference in size, weight or coefficient of friction. However, in the continuous operation process of the machine of the prior art, the extruded viscous resin is inevitably adhered to the working surfaces of the rolling roller and the separating roller set, the continuously thickened resin layer can obviously change the effective working diameter and the surface morphology of the roller, and the preset rolling gap and the preset separating gap are caused to deviate, so that the rolling pressure is misaligned, in addition, uneven resin adhesion can damage the dynamic balance of the roller, vibration and noise increase during the running of equipment are caused, the load fluctuation of a driving motor is increased, the energy consumption is increased during long-term running, and long-term stable, efficient and high-quality running of the equipment cannot be ensured. Disclosure of Invention The invention aims at solving the problems in the prior art and provides a torreya peeling separator. The aim of the invention can be achieved by the following technical scheme: The Chinese torreya peeling separator comprises a machine body, wherein a feed inlet is formed in the upper portion of the machine body, and a plurality of peeling machines are sequentially arranged below the feed inlet: The peeling mechanism comprises two groups of rolling rollers which are rotatably connected in the machine body and are parallel to each other, a rolling channel for breaking torreya exocarp is formed between the rolling rollers, and the rolling rollers are driven to rotate by a first driver; The separating mechanism comprises a separating roller set which is rotatably connected in the machine body, the separating roller set is connected below the rolling channel and can further strip the epicarp and output the epicarp and the pit in a classified manner, and the separating roller set is driven to rotate by a second driver; The machine body is also provided with a low-temperature embrittlement cleaning structure for removing torreya resin stuck on the rolling roller and the separating roller set. According to the invention, automatic peeling and separating treatment of Chinese torreya fruits can be realized, chinese torreya fruits enter from a feed inlet, firstly, the Chinese torreya fruits pass through a grinding channel formed by two sets of grinding rollers which rotate oppositely, the outer peel is crushed to realize preliminary peeling, then, the peel kernels with part of the peel and the separated outer peel fall into a separating roller set below together, the released outer peel and the hard peel kernels are thoroughly separated under the friction effect between the separating roller sets, and the peel and the fruit are guided and output respectively. Moreover, this scheme has integrated low temperature embrittlement cleaning structure in particular, utilizes the low temperature to make the resin embrittlement of adhesion at the roller surface, shrink to easily by the cleaing away, and get rid of the resin and the peel fibre of sticking and hanging on the roller through the abluent mode of impact, ensure equipment can continuous and stable operation for a long time, avoided the efficiency decline, the nuclear pollution scheduling problem that lead to because of the resin adhesion, realized the integration of high-efficient peeling separation and automatic clean maintenance. In the torreya peeling separator, the low-temperatur
