Problems solved by technology

Although microwave has the advantages of fast heating speed, short drying time, high energy utilization rate and easy control, but only using microwave for drying is prone to burns and food edge coking, crusting and hardening due to overheating, which makes the scrap rate Large, and the method is cumbersome, and repeated cooling and heating are required, which increases the workload
[0005] At present, another example is Chinese patent application 201210281159.6, which discloses a method of repeatedly heating and drying Luo Han Guo using vacuum microwaves and infrared rays. Higher, the quality is higher, but the high temperature makes the economic cost high, and the repeated operation makes the process cumbersome, the processing volume is small, and the cost increases

Embodiment 1

[0035] (1) After washing, put a fresh Luo Han Guo into steam at 100°C for 2 to 3 minutes, then take it out and automatically lower it to normal temperature.

[0036] (2) Then make a small hole with a diameter of 1mm and a depth of 2.5cm in the center of the Luo Han Guo and the corresponding bottom, put it into a freezer at a temperature of -30~-35°C, freeze for 1.2 hours and take it out. Then put the Luo Han Guo into the material tank of the tray, set the vacuum degree in the microwave dryer to -0.078Mpa, and the temperature to 45°C, put the tray in the microwave dryer and turn on the motor, so that the motor rotates at 3-8 The speed per minute drives the tray to rotate, dehydrating and drying for 30 minutes.

[0037] (3) Then put the Luo Han Guo obtained in step 2 into the heat pump drying equipment with a temperature of 30°C and a humidity of 10%, and dry and dehydrate for 8 hours.

[0038] The improved Mangosteen process makes the processing control simple, and it is conve...

Embodiment 2

[0040] (1) Wash a fresh Luo Han Guo and put it into steam at a temperature of 95°C for 2 to 3 minutes, then take it out and automatically lower it to room temperature.

[0041] (2) Then cut the grosvenor fruit in half at the top of the pedicle, put it in a freezer at a temperature of -30~-35°C, freeze it for 1 hour and take it out, then put the grosvenor fruit into the material tank of the tray, set The vacuum degree in the microwave dryer is -0.068Mpa and the temperature is 30°C. Put the tray in the microwave dryer and turn on the motor, so that the motor drives the tray to rotate at a speed of 3-8 rpm, and dehydrate and dry for 25 minutes.

[0042] (3) Then put the Luo Han Guo obtained in step 2 into the heat pump drying equipment that has been set at a temperature of 30°C and a humidity of 10%, and dry and dehydrate for 7 hours.

[0043] In addition to possessing the advantages of Embodiment 1, the process has a drying time and drying temperature less than that of Embodimen...

Abstract

The invention discloses a momordica grosvenori drying process which comprises the following steps: cleaning fresh momordica grosvenori, putting the momordica grosvenori in steam at the temperature of 90-110 DEG C to deactivate enzyme for 2-3 minutes; freezing the momordica grosvenori subjected to enzyme deactivation under the condition of the temperature of 30-35 DEG C below zero for 1-1.5 hours, and performing vacuum low-temperature dehydration on the momordica grosvenori in vacuum microwave drying equipment for 30-35 minutes; and finally, drying the treated momordica grosvenori under the conditions of the temperature of 30-50 DEG C and the humidity of 10-15 percent for 6-10 hours. According to the improved momordica grosvenori process, the momordica grosvenori processing yield and the momordica grosvenori processing quality are improved, the cost and the energy are saved, and the momordica grosvenori is industrially processed and dried in a large scale.

Description

technical field [0001] The invention relates to a drying process and equipment for Luo Han Guo. Background technique [0002] Luo Han Guo is the fruit of the Cucurbitaceae plant Luo Han Guo. It is known as the "fairy fruit". It is mainly produced in Guilin, Guangxi. The fruit has high nutritional value and is rich in vitamin C, glycosides, fructose, glucose, protein, lipids, etc. Luo Han Guo is sweet in taste and cool in nature, and belongs to the lung and large intestine meridian. [0003] Because the fresh fruit of Luo Han Guo is not easy to preserve, all growers will dry the picked fresh fruit or store it after further deep processing. Among them, the drying method is like the invention patent with the publication number of CN1631273, which discloses a method of baking and processing Luo Han Guo. Luo Han Guo fruits are loaded into the mobile multi-layer three-dimensional fruit plate rack according to the large, medium and small sizes, and the fruit plate rack is pushed i...
