Technical Field

The invention relates to the technical field of pumpkin seed production, in particular to a water moistening process for pumpkin seed shelling.

Background

The pumpkin seeds are in a flat oval shape, one end of each pumpkin seed is slightly sharp, the appearance of each pumpkin seed is yellowish white, edges of each pumpkin seed are slightly ridged, the length of each pumpkin seed ranges from 1.2 cm to 2 cm, the width of each pumpkin seed ranges from 0.7 cm to 1.2 cm, hairy antler is arranged on the surface of each pumpkin seed, the edges of each pumpkin seed are more, and the pumpkin seeds are popular with consumers as one of various types of the pumpkin seeds and belong to common snacks.

Pumpkin seeds need to pass through a plurality of steps in the production and processing process, and can finally become delicious snacks, the steps include soaking water, feeding, cooking, drying and the like, the step of shelling is to remove all the outer skins of the pumpkin seeds, the operation of mechanical shelling is relatively harsh, if the outer shells of the pumpkin seeds are relatively dry, then the shelling process can break the original intact shelled melon seeds, if quantitative water is added before shelling to stir and moisten water, the water adding operation is relatively complex, firstly, quantitative melon seeds need to be specified, water with corresponding volumes is weighed, the manual operation is complex, the working efficiency is low, misoperation can easily occur, and the final quality and taste of the pumpkin seeds are influenced.

Consequently design an automatic designated weight raw materials of weighing, directly perceived weighing water level volume, automatic mixing stirring raw materials and water simplify the step of adding water, guarantee the appropriate moisture content of melon seed moisture, improve work efficiency, the moist water installation of the integrity when guaranteeing the melon seed shelling, the problem that the inventor will solve.

Disclosure of Invention

Aiming at the defects of the prior art, the invention aims to provide a water moistening process for shelling pumpkin seeds, which can realize the functions of automatically weighing raw materials with specified weight, intuitively weighing water level volume, automatically mixing and stirring the raw materials and water, simplifying the water adding step, ensuring proper moisture content of water in the pumpkin seeds, improving the working efficiency and ensuring the completeness of the shelled pumpkin seeds.

The technical scheme adopted by the invention for solving the technical problems is as follows: a water moistening process for shelling pumpkin seeds comprises the following steps:

(1) the pumpkin seeds of the raw material are transferred to a transfer bin for standby after being screened, graded, stone-removed and color-selected;

(2) conveying the materials obtained in the step into a raw material bin of a stirrer through air conveying for storage;

(3) weighing the materials obtained in the above steps by an electronic scale integrated on a stirrer, and stopping feeding by wind when the weight of the materials meets the requirement;

(4) enabling water from a water source to flow into the high-level water tank through the water inlet pipe, feeding water into the high-level water tank, observing the water level condition through the water level pipe, closing the water inlet valve when the water level reaches the required water level scale, and stopping feeding water, wherein the water capacity in the high-level water tank is two times of the weight of the material obtained in the step (3);

(5) operating the air cylinder, opening a bin door of the raw material bin, and putting the material obtained in the step (3) into a stirring bin;

(6) operating a valve, opening a water outlet pipe of the high-level water tank, and putting water in the high-level water tank into the stirring bin;

(7) starting a stirring motor to stir the mixture of water and materials, wherein the water content is 18-20%, the material moistening time is 4-7h in winter and 2.5-4h in summer, and the stirring is carried out once every 30min, and each stirring time is 30 min;

(8) and (3) draining the materials obtained in the step, and conveying the materials to a centrifugal husking machine for husking.

Further, the weight of the raw materials entering the raw material bin in the step (2) is 20-50 kg.

Further, the emptying and waterproof operations of the step (5) and the step (6) are carried out simultaneously.

Further, the stirring frequency in the step (7) is not less than two times.

Further, the water temperature in the step (4) is not lower than ℃.

The invention has the beneficial effects that:

1. according to the invention, by adjusting the weight ratio of the pumpkin seeds to the water and controlling the total weight of the pumpkin seeds stirred in the quantitative container every time, the pumpkin seeds and the water are moisturized in an optimum ratio and weight, the moisturizing effect is improved, the shells of the pumpkin seeds are easier to separate, and the operation is more standard, convenient and quick.

2. According to the invention, water is sprayed down through the annular spraying pipe, and stirring is kept in the water spraying process, so that the functions of improving the water moistening efficiency and shortening the water moistening time are realized.
