Problems solved by technology

At present, there is also the application of this method in cereals, such as CN101138371A (a kind of brown rice tea beverage and its preparation method). The raw material of this invention makes the nutrients in the raw material separate out by enzymolysis technology, and the solid matter after vacuum concentration is spray-dried. into a solid brown rice tea beverage. This product discards water-soluble substances and reduces nutritional content. At the same time, the process is too complicated and the production cost is high.

Embodiment 1

[0092] Embodiment 1 production process example

[0093] Step 1: Take 130 kilograms of cleaned rice (commercially available), crush it, take the material that has passed through 20 meshes and not passed through 80 mesh sieves, the particle size is 0.18-0.85mm, and about 100 kilograms of rice flour particles are obtained, and set aside;

[0094] Step 2: Add 9 kg of water to the above rice flour granules, soak at room temperature (30° C.) for 60 minutes to allow the material to absorb part of the water, and obtain material 1 with a water content of 21.1% (wet basis).

[0095] Step 3: The material obtained in step 2 was roasted at 120°C for 50 minutes to obtain material 2.

[0096] Step 4: Superfinely pulverize the roasted material with a superfine pulverizer (purchased from Beijing Kaikai Duobang Technology Co., Ltd.; model: ZM-50), the average particle size of the pulverized material is 35 μm, and the material is obtained 3.

[0097] Step 5: Weigh 0.3 kg of dried seedless juju...

Embodiment 2

[0109] Embodiment 2: The molding mode of cereal instant tea is an example

[0110] According to the preparation steps of Example 1. In this embodiment, only the molding step 8, that is, the molding method test of the product, is changed. The three molding methods are exemplified as follows:

[0111] (1) Using a granulator (purchased from Taizhou Bojing Pharmaceutical Machinery Co., Ltd., Jiangsu Province, model: Y6-60) to process and shape the material 3 into granules (particle size: 0.5 mm).

[0112] (2) Use a spray granulation fluidized bed dryer (purchased from Hangzhou Qianjiang Drying Equipment Co., Ltd., Zhejiang Province, model: GLZ) to granulate, control the wind speed to 4m / s, transport concentration to 1.5, and temperature to 45°C. The agent flow rate is 0.0012kg / kg material, and the spray pressure is 1.5MPa (particle size is 0.3mm).

[0113] (3) Use a single-punch tablet press (purchased from Guangzhou Kangnuo Pharmaceutical Machinery Co., Ltd., Guangdong Province...

Embodiment 3

[0115] Embodiment 3: Example of the drying method of cereal instant tea

[0116] According to the preparation steps of Example 1. In this embodiment, only step 9 is changed, that is, the drying and cooling method test of the formed material. The three drying and cooling methods are as follows:

[0117] (1) Dry the molded material with hot air in a hot air drying test box at 45°C, with a relative humidity of 35%, and a wind speed of 1m / s (purchased from Dongguan Enterprise Industrial Equipment Manufacturing Factory, Guangdong Province) for 45 minutes, and then cool to room temperature , so that the water content is 12.2% (wet basis).

[0118] (2) After forming the material, at 1.2kW·kg -1 Microwave drying in microwave chemical raw material drying equipment (purchased from Guangzhou Wenbo Industrial Co., Ltd.) took 38 minutes to dry, and cooled to room temperature to make the water content 11.42% (wet basis).

[0119] (3) Dry the formed material with a spray granulation fluid...

Abstract

The invention belongs to the technical field of foodstuff processing, and concretely relates to a cereal instant tea and a production method thereof. The instant tea provided by the invention comprises the following raw materials: ultrafine grinded cereal materials, ingredients, soluble starch, NaHCO3 and water, wherein the cereal is selected from rice, broken rice, buckwheat, millet, corn or barley and combinations thereof, and the ingredients are red date, matrimony vine, radix codonopsis, safflower, etc. The cereal and the ingredient are grinded into ultrafine particles with a size of less than 100 [mu]m. The production method comprises immersing the cereal with water, draining water, roasting, ultrafinely grinding the roasted cereal and the ingredients, mixing the grinded cereal and the ingredients with the NaHCO3, adding a binder, uniformly mixing, molding, drying and cooling to obtain the product. The product provided by the invention is quick in dissolving speed, and high in digestion and absorption rate, and has a unique cereal fragrance.

Description

technical field [0001] The invention belongs to the technical field of food processing, and in particular relates to a grain deep-processing product and method, in particular to a grain instant tea and a production method thereof. Background technique [0002] Tea drinks made from roasted grains can increase the content of water-soluble components and produce a strong grain burnt flavor. At the same time, it has the effects of invigorating the spleen and dampness, appetizing and improving intelligence, calming the heart and promoting blood circulation, nourishing the heart and calming the nerves (Jin Haizhu, publication number is CN1559301A, rice beverage and preparation method thereof; Sun Bo, publication number is CN101606558A, a kind of millet and its processing method. The applicant has invented and disclosed "a production method and product of convenient nutritious rice tea" (the publication number is CN101103755A), the steps include washing, roasting, and crushing raw ...
