Fruit shelling device and shell and seed separator comprising the shelling device

Abstract

The present invention discloses a fruit shelling device and a shell and seed separator comprising the shelling device, and belongs to the field of agricultural machinery. The fruit shelling device comprises a closed and internally accommodating shelling cavity body; the shelling cavity body conducts air bath heating for contents under a certain pressure difference condition for shelling; heat source for heating is arranged outside the shelling cavity body; and the heat source is thermally conducted to the interior of the cavity body through the outer wall of the shelling cavity body. The fruitshelling device and the shell and seed separator comprising the shelling device use a drying principle to conduct the fruit shelling, can avoid carbonization of fruit peels, fruit pulp, etc. in the shelling processes, ensure the homogeneous degree of the shelling effects, are suitable for fruits with the relatively high water content fruit peels and high-temperature easy carbonized fruit pulps oftea-seed oil Chinese olives, etc., further ensure the quality of the raw materials in the processes of subsequent fruit pulp extraction, oil extraction, etc., improve the extraction rate of the beneficial substances in the fruit pulp, the oil yield of the fruit pulp, etc., and improve the separation efficiency and effects of the shelling.

Description

technical field [0001] The invention relates to an agricultural machine, in particular to a fruit shelling device and a shell and seed separator comprising the shelling device. Background technique [0002] Generally, sun-drying is usually used for the husking treatment of fruits, and after the husks are naturally burst, the husk seeds are manually sorted. The technical content of the shelling and separation is low, the time is long, and it is affected by the weather, the efficiency is low, and the labor cost is high. In order to improve the efficiency of shelling and separation, some shelling machines with different structures have appeared in the prior art. Although they are all shelling and sorting based on the principle of first shelling and then vibration separation, the shelling principles adopted by different shelling machines Not the same. [0003] Such as application number CN201711402945.6 Invention name: flexible walnut shelling machine, a disclosed shelling mac...

Problems solved by technology

[0007] Another method of shelling camellia oleifera green fruit by rubbing shelling. Because the tea seeds are small, the peel is hard, and the fruit size uniformity is poor, it is difficult to find a suitable rubbing structure and the intensity of rubbing is also difficult to control. If Strong force will lead to a greater degree of peel rupture and severe fragmentation, which will not only bring great difficulty to the separation of tea seeds, but also cause a large number of tea seeds to rupture, thereby affecting the oil yield; but if the peel is poorly ruptured , peeling effect is not good, it will still affect the final oil yield

Such as application number CN201510302696.8 invention name A kind of shelling and cleaning process of camellia oleifera fruit, which adopts rubbing type shelling. This technology can only shell the green fruits with relatively uniform size. During the shelling process, part of the camellia oil green fruit is extruded from the kneading structure; on the other hand, the shell of the camellia oleifera green fruit has a high water content. During the extrusion process, a large amount of water is released from the shell, and it is easy to agglomerate and block in the sheller after the shell is broken. , will have a great negative impact on the subsequent separation of tea seeds
