Problems solved by technology

[0003] Walnut is also a kind of nut that people like, and it is rich in nutrition, but what people generally see is only the air-dried one.
Fresh walnuts can only be eaten in autumn when they are ripe. After this period, fresh walnuts cannot be eaten. Therefore, fresh walnuts have become a delicacy that can only be savored in other seasons. The technology is not simple, environmentally friendly, economical, efficient, or difficult to achieve the expected freshness preservation effect

Embodiment 1

[0020] see figure 1 , the fresh-keeping treatment method of walnut soaked in wax according to the present invention, after the mature walnuts are picked, the peeling treatment is carried out manually or mechanically, and then rinsing and air-drying are carried out in time, and the walnuts after the rinsing and air-drying are sterilized by flame method, and the flame sterilized During the process, the speed of the material is controlled and the material is rolled so that the walnuts quickly pass through the flame zone. The sterilization temperature in the flame zone is controlled at 800-900 degrees, and the sterilization time is 3-6 seconds; after sterilization, it enters the wax pool for waxing treatment. Then air cool down.

[0021] The walnuts can be well kept fresh by adopting high-temperature flame instant sterilization and soaking in wax. At room temperature, fresh walnuts can be preserved for more than 180 days. Energy saving and environmental protection, enabling cons...

Embodiment 2

[0023] see figure 1 , the walnut dipping wax fresh-keeping treatment method of the present embodiment is different from Embodiment 1 in that: further, the walnuts after flame sterilization enter the wax pond, the temperature of the wax pond is controlled at 85-95 degrees, and the wax dipping time is controlled at 3-8 seconds, use 58-62° food-grade refined paraffin wax, immediately air-cool the walnuts out of the wax pool, and carry out grading treatment while air-cooling and cooling. Grading is graded by diameter. After grading, it is packaged and put into storage according to the level.

Embodiment 3

[0025] see figure 1 , the walnut dipping wax fresh-keeping treatment method of the present embodiment, differs from embodiment 1 in that: the walnuts after the green peeling treatment are soaked in an aeration tank for 2 to 3 minutes, and then rinsed with high-pressure water spray, and the walnuts after rinsing Perform air-drying treatment, and sterilize in time after cooling down to room temperature. The air-drying process adopts natural air-drying or artificial physical air-drying; artificial physical air-drying temperature is 70-85 degrees, wind speed is 4-6 m / s, and air drying time is 30-60 seconds.

Abstract

The invention relates to a waxdip based walnut freshness retaining method. The waxdip based walnut freshness retaining method includes the following steps of husking mature walnuts after picking, timely rinsing and air-drying the walnut kernels, sterilizing the rinsed and air-dried walnut kernels according to a flame method, controlling the material feeding speed, and rolling the walnut kernels topass through a flame region quickly, wherein the sterilization temperature in the flame region is controlled at 800-900 DEG C, and the sterilization time is 3-6 seconds; after sterilization, allowingthe walnut kernels to enter a wax tank for wax dipping, and performing air cooling. Complete equipment for walnut freshness retaining based on waxdip comprises a walnut husking machine, an aeration tank, a spraying facility, a flame sterilization device and the wax tank. After husking, the newly-picked mature walnuts are fed into the aeration tank to be soaked; the soaked walnut kernels are cleaned through spray by the spraying facility, and then fed into an air-drying device; the air-dried and cooled walnut kernels are fed into the flame sterilization device to be sterilized; an outlet of the flame sterilization device is connected with the wax tank. The waxdip based walnut freshness retaining method has the advantages of environmental protection, no pollution, high speed, easy operation, good sterilization effect, and capability of storing the fresh walnuts for 180 days or more.

Description

technical field [0001] The invention relates to a fresh-keeping method for walnuts and a complete set of fresh-keeping treatment equipment, which are used for fresh-keeping treatment of walnuts.
