Embodiment 1

[0023] (1) Garlic pretreatment: Pour the garlic on the garlic selection table, remove the moth-eaten, mildewed, and undersized garlic, then use a cutting machine to cut the garlic, pour the chopped garlic cloves on the elevator, and The conveyor belt is sent to the splitter for splitting. After the split garlic is dried off-line, the outer coat and transparent film of the garlic cloves are removed, and the unremoved garlic skins are manually picked out. Finally, cut into cube garlic grains with a side length of 5mm with a multi-kinetic dicing machine.

[0024] (2) Plate loading: Take three material plates, each plate is covered with 2 layers of material, the material in the middle of the plate is slightly thinner, and the periphery is slightly thicker.

[0025] (3) Pre-freezing: put the material into the freezer after packing, let the material pre-freeze at a temperature of -30°C, keep it at this temperature for 4 hours, and reduce the temperature of the material to the eutec...

Finally, cut into cube garlic grains with a side length of 5mm with a multi-kinetic dicing machine.

[0031] (2) Plate loading: Take three material plates, each plate is covered with 2 layers of material, the material in the middle of the plate is slightly thinner, and the periphery is slightly thicker.

[0032] (3) Pre-freezing: put the material into the freezer after packing, let the material pre-freeze at a temperature of -25°C, keep it at this temperature for 4 hours, and reduce the temperature of the material to the eutec...

Embodiment 3

[0037] Garlic granules processed in different ways were compared.

[0038] The processing flow of garlic granules in the vacuum freeze-drying group is through material selection, stalk cutting, peeling, and dicing machine to cut garlic granules into cubes with a side length of 5mm, and then put them on a plate with 2 layers. The loaded material is put into the freezer, and the material is pre-frozen at a temperature of -30°C, and kept at this temperature for 4 hours, and the temperature of the material is lowered to the eutectic point. Lower the temperature of the cold trap to -45°C in advance, put the material into the freeze-drying bin, vacuumize to 10Pa, and then carry out vacuum freeze-drying. After reaching the safe moisture with a moisture content of 6% or less, the drying ends.

[0039] The processing process of garlic granules in the microwave vacuum drying group is through material selection, stalk cutting, peeling, and dicing machine to cut garlic granules into cube...

Abstract

The invention discloses a method for processing garlic granules through vacuum freezing and microwave vacuum serial combined drying, belonging to the key technical field of garlic deep processing. The method comprises the steps of selecting raw materials, cutting off bases, removing skins, cutting the raw materials into cubic garlic granules with length of side being 5mm by using a dicer and containing the diced materials in trays at two layers; after the diced materials are contained in the trays, pre-freezing at negative 20DEG C for 4 hours; after pre-freezing is finished, reducing the temperature of a cold trap to negative 45DEG C to negative 35DEG C in advance, placing the materials in a freeze-drying chamber, vacuumizing the freeze-drying chamber to be below 12Pa for vacuum freeze-drying, and stopping vacuum freeze-drying after approximate 7 hours till the water content is 30 percent; taking out the trays, immediately placing the trays in a microwave vacuum drying machine, starting up a vacuum pump, starting microwave when vacuum degree reaches 90KPa to 120KPa for drying 15-20 minutes under the condition of power being 420W, and stopping drying after the safe water content isbelow 6 percent. Not only can the garlic granules obtained by adopting the drying process reserve the excellent quality of common vacuum freeze-dried garlic granules, but also the time of vacuum freeze-drying process is shorted and the energy consumption is reduced.

Description

1. Technical field [0001] The invention relates to a processing method for drying garlic grains combined with vacuum freezing and microwave vacuum in series, and belongs to the key technical field of garlic deep processing. 2. Background technology [0002] Garlic belongs to the Liliaceae plant. Its bulb is called garlic head, leaf stem is called green garlic or garlic seedling, and flower stem is called garlic sprout. It is a delicious product that people like. Garlic also has special physiological functions, not only can be used as seasoning and health food, such as: garlic sauce, garlic powder, minced garlic, garlic beer, garlic soy sauce, etc., but also a good material for medical medicine, known as "natural broad-spectrum bactericidal It has the functions of sterilization, anti-inflammation, deworming, invigorating the stomach, analgesia, relieving cough and eliminating phlegm. In addition, garlic contains germanium and selenium, which are high anti-cancer components. ...
