Description

Red date deep processing, sewage treatment and jujube pit recycling composite device

Technical Field

The invention relates to a fresh red date processing device. In particular to a compound device for deep processing of red dates, sewage treatment and recycling of date pits.

Background

Xinjiang red dates are a special fruit in Xinjiang and belong to the genus of Ziziphus in the family of Prunaceae. Xinjiang belongs to typical continental climate, the illumination time is long, the day and night temperature difference is large, and less rain is generated after drying, so that the planted Xinjiang red dates have the advantages of full fruits, thin peel, dark red peel, sweet taste and the like compared with red dates in other areas, and have the effects of tonifying qi, nourishing blood and soothing the nerves.

The planting area of the Xinjiang red dates breaks through the 700-ten-thousand mu customs and accounts for more than one third of the planting area of the national red dates. Xinjiang red date planting has become the mainstay of local economy. However, the water content of the red dates is as high as more than 80%, the fresh red dates are short in storage time after being picked, are rotten after being dehydrated, are easy to ferment, are not easy to store and transport, seriously affect circulation and sale, have few and few deep processing items and bring huge economic loss to local jujube farmers.

In recent years, research reports that a method for processing fresh red dates into dried red dates and date powder or a method for further processing the dried red dates provide ideas for further processing and utilization of the red dates.

However, a whole set of deep processing device does not exist so far, and the deep processing project of Xinjiang fresh red dates has wide requirements.

When the jujube pulp separating machine is used, firstly, softened red jujubes are placed inside the pulping tank 9-7, then the motor 9-3 is started, the motor 9-3 drives the pulping rod 9-5 to rotate, at the moment, the pulping blades 9-8 on the pulping rod 9-5 can smash the softened red jujubes to separate jujube pulp from jujube pits, and because the softened red jujubes are cooked by water, the jujube pulp is very easy to smash into pulp to further separate jujube peel from jujube pulp. Part of the jujube pulp directly flows downwards along the meshes on the second filter screen 9-12 to sequentially pass through the concentric hollowed-out rings 9-21 on the nuclear mud primary centrifugal separation discs 9-16 and the concentric hollowed-out rings 9-21 on the bottoms of the nuclear mud secondary separation cylinders 9-18 to enter the inner tanks 9-15, is further smashed under the action of the pulping blades 9-23 and then enters the inner tanks 9-15 below the pulp filtering meshes 9-24 through the meshes on the pulp filtering meshes 9-24, the other part of the jujube pulp flows downwards respectively through the concentric hollowed-out rings 9-21 on the nuclear mud primary centrifugal separation discs 9-16 and the concentric hollowed-out rings 9-21 on the bottoms of the nuclear mud secondary separation cylinders 9-18 to sequentially enter the inner tanks 9-15 through the meshes on the third filter screen 9-10 and the first filter screen 9-11, and further broken under the action of the beating blades 9-23 and then enters the inner tank 9-15 below the pulp filtering net 9-24 through meshes on the pulp filtering net 9-24; because the softened red dates are easy to pulp, and the pulp particles of the red dates produced after pulping do not have larger volume and mass, the centrifugal force of the pulp particles of the red dates on the primary centrifugal separation disc 9-16 of the pit mud and the secondary centrifugal separation cylinder 9-18 of the pit mud is smaller, so that most of the pulp of the red dates can finally enter the inner tank 9-15.

Because the aperture of the meshes on the second filter screen 9-12 is smaller, the jujube pits can only fall down to the first nuclear mud centrifugal separation disc 9-16 far away from the center of the first nuclear mud centrifugal separation disc 9-16 through the meshes on the third filter screen 9-10 and the first filter screen 9-11, the first nuclear mud centrifugal separation disc 9-16 and the beating rod 9-5 synchronously rotate together, the width of the concentric hollow ring 9-21 on the first nuclear mud centrifugal separation disc 9-16 is smaller, the jujube pits move to the edge of the first nuclear mud centrifugal separation disc 9-16 under the action of centrifugal force and fall on the bottom of the second nuclear mud separation cylinder 9-18 and far away from the center of the bottom of the second nuclear mud separation cylinder 9-18, the second nuclear mud separation cylinder 9-18 and the beating rod 9-5 synchronously rotate together, so that the date pits move to the bottom edge of the pit mud secondary separation cylinder 9-18 under the action of centrifugal force and fall into the outer tank 9-13 through the date pit falling holes 9-19.

The density of the jujube peel is smaller than that of the jujube pit, and the volume of the jujube peel is not very large, so that the centrifugal force on the bottoms of the first centrifugal separating discs 9-16 of the pit mud and the second centrifugal separating cylinders 9-18 of the pit mud is also relatively small, the jujube peel with small volume can enter the inner tanks 9-15, and the jujube peel with large volume and incapable of falling through the concentric hollow rings 9-21 can enter the outer tanks 9-13 along with the jujube pit under the action of the centrifugal force.

In the invention, the diameters of the filter screen plates 9-9, the pit mud primary centrifugal separation discs 9-16 and the pit mud secondary separation cylinders 9-18 are gradually increased, the characteristic of higher mass of the jujube pits is fully utilized, the jujube pits falling from the filter screen plates 9-9 to the pit mud primary centrifugal separation discs 9-16 are far away from the centers of the pit mud primary centrifugal separation discs 9-16, and the centrifugal radius of the jujube pits falling from the pit mud primary centrifugal separation discs 9-16 to the cylinder bottoms of the pit mud secondary separation cylinders 9-18 is further increased, so that the jujube pits can be thoroughly separated from the jujube pulp, and the jujube pits are prevented from being doped in the jujube pulp. By utilizing the double-channel beating machine, the 100% separation of the date pits and the date pulp can be realized, and the date pits doped in the date pulp can be thoroughly avoided.
