Problems solved by technology

However, the continuous degree of this method is not high, and the drying time of the pulp after pitting is long, and because the jujube itself contains a variety of sugars, if the drying is not thorough, the crushing will not be smooth, so it is necessary to develop a method that can process the jujube. The method of continuous de-nucleating and drying improves applicability

Embodiment 1

[0019] This embodiment provides a method for one-time pulverization, denucleation and drying of jujubes to make powder. Specifically, jujubes are processed and swollen with a treatment solution and then pulverized. The pulverization is carried out by destroying only the pulp without destroying the core. Then the pulp is separated from the core, and then the pulp is collected and dried to make powder. The treatment liquid can be water or other liquids that will not affect the quality and use of jujubes. The purpose is to make the pulp of jujubes swell and soften, which is convenient for later crushing and separation. During the crushing process, ensure that the crushing force will not affect the core. Only the pulp can be destroyed without destroying the core. Usually, crushing can be carried out by squeezing and kneading, so that the pulp is destroyed and the integrity of the core is guaranteed. In the above de-pitting process, the separation of the pulp and the core can be ca...

Embodiment 2

[0021] This embodiment is a further improvement on the basis of Example 1, wherein first the jujubes are soaked in the treatment solution, and heated so that the treatment solution is rapidly immersed in the jujubes to achieve swelling. The heating temperature should not exceed 50°C, preferably at 30- Between 50°C, this can quickly make jujubes swell, which is convenient for subsequent processing. The treatment solution used in this embodiment is a mixture of ethanol and water, wherein the mass ratio of water to ethanol to water is 1:8-10. After jujubes reach swelling, the presence of ethanol can make the pulp more crisp and easier Subsequent crushing and separation operations, and in the later drying process of the pulp, due to the presence of ethanol, will speed up the drying speed and improve the fluidity of the dry powder. During the drying process, the drying temperature is controlled at 60-70°C, so as not to damage the nutrients in the pulp due to excessive temperature. ...

Embodiment 3

[0023] Through the one-time crushing, denucleating and drying method of jujubes provided by the present invention, the test operation is carried out in the workshop, and the swollen jujubes are directly sent into the pulverizer through the conveyor belt, and the pulverizer is used to pulverize the pulp through steel wire rollers After the pulp is crushed, it is conveyed together with the core through the conveyor belt with a large number of gaps above. During the transmission process, the pulp is separated through the gap and collected for drying. The core is sent to the collection bucket by the conveyor belt, and the pulp is sent to drying after collection. Drying is carried out in the device, and the drying temperature does not exceed 70°C. After drying, the jujube powder is obtained, and the powder can be processed according to the actual situation to obtain the product.

Abstract

The invention discloses a method for powder making by one-time crushing, pit removal and drying of ziziphus jujuba. The method includes: treating and swelling ziziphus jujuba with a treatment solution, then conducting crushing treatment by the way of only destroying flesh without destroying pit, then separating the flesh from the pit, then collecting the flesh, and conducting drying and powder making. According to the invention, through previous crushing, the flesh is in a crushed state before drying, thus increasing later drying efficiency, at the same time, the method effectively realizes one-time operation of ziziphus jujuba crushing and pit removal, and has the advantages of simple technological process, strong realizability, and industrial on-line automatic operation.

Description

technical field [0001] The invention belongs to a treatment method for stone fruits, in particular to a method for one-time crushing, depiting and drying of jujubes to make powder. Background technique [0002] Jujube (scientific name: Ziziphus jujuba Mill.), also known as jujube, jujube, jujube, jujube. Rhamnaceae Jujube plants, deciduous small trees, sparse shrubs, up to 10 meters high, bark brown or taupe, petioles 1-6 mm long, or up to 1 cm on long branches, glabrous or sparse Hair, stipules slender, often shedding later. Flowers yellow-green, bisexual, glabrous, with short peduncles, solitary or densely formed into axillary cymes. Drupe oblong or long oval, 2-3.5 cm long, 1.5-2 cm in diameter, red when ripe, later turning reddish purple, mesocarp fleshy, thick, sweet. Seeds are oblong, about 1 cm long and 8 mm wide. Dates are rich in vitamin C and vitamin P. In addition to fresh food, they can often be made into candied dates, red dates, smoked dates, black dates, w...
