Embodiment Construction

[0023] The patent will be further described below in conjunction with the accompanying drawings and embodiments.

[0024] Such as figure 2 A kind of device and method for improving the uniformity of almond radio frequency sterilization of the present invention consists of a first layer of almond container 1, a second layer of almond container 2, a third layer of almond container 3, a fourth layer of almond Almond wood container 4, the 5th layer almond wood container 5 form.

[0025] Specific working process: refer to figure 1 and Figure 4 ;

[0026] Step S10: Arranging 5 layers of containers in sequence. First, the almond with a water content of 10% and a total weight of 1.5Kg is divided into 5 parts on average, and each part of almond of 0.3Kg is put into each layer of containers, and the capacity of each layer of containers is 30.0 Length × 22.0 width × 2.0 height cm³, the first layer of almond wood container 1, the second layer of almond wood container 2, the third l...

Abstract

The invention discloses a device and method for improving radio frequency sterilizing uniformity for almonds. The apparatus comprises a first tier of almond container, a second tier of almond container, a third tier of almond container, a third tier of almond container, a fourth tier of almond container and a fifth tier of almond container. The method comprises the steps of placing the five tiers of almond container in sequence; heating almonds for 3 min by hot air assisted radio frequency; placing the five tiers of almond container in reverse direction; heating the almonds for 3 min by hot air assisted radio frequency; stopping heating the almonds by radio frequency, and holding the temperature of 72 DEG C for 15 min by hot air; stopping temperature holding by hot air, and cooling quickly to room temperature. By using the apparatus and method, nutrition loss in almonds in corners of the containers due to too high temperature is avoided, and the almonds can be heated more evenly in radio frequency treatment.

Description

technical field [0001] The invention relates to the technical field of radio frequency sterilization of fruit seeds, in particular to a device and method for improving the uniformity of radio frequency sterilization of almonds. Background technique [0002] According to the United Nations Food and Agriculture Organization's statistical database (FAOSTAT), the output of almonds in six countries including the United States, Spain, Australia, Italy, Turkey and China ranks among the top in the world. Studies have shown that almonds contain high levels of unsaturated fatty acids such as linoleic acid and linolenic acid and vitamin E, and have high nutritional and medical values. Therefore, almonds are widely accepted and loved by consumers. At present, California, USA is the largest almond supplier in the world. During the harvesting process of almonds, there are methods such as vibrating mature almonds from the tree, drying almonds on the ground naturally or drying the dried alm...
