Problems solved by technology

In particular, it is difficult to finely pulverize into a stable particle size distribution because the difference in lipid and sugar quality significantly affects the pulverization conditions

Embodiment Construction

[0056] Embodiments of the present invention will be described below.

[0057] figure 1 1 is an explanatory diagram of the first embodiment of the present invention, 1 is a raw material hopper, 2 is a raw material supply machine, 3 is a jet mill, 4 is a suction duct, and 5 is a pulverized material recovery hopper. In addition, although the raw material used in each embodiment is soybean, it may be other grains, such as adzuki bean and rice.

[0058] Soybeans as a raw material are fed from a raw material hopper 1 to a raw material feeder 2 installed therebelow, and are then supplied to a jet mill 3 . The raw material feeder 2 is a vibrating quantitative supply device, and its raw material supply amount is controlled by the control device 6 as will be described later.

[0059] figure 2 Details of the jet mill 3 are given. The jet mill 3 has a casing 9 including a cylindrical main body 7 and a conical front cover 8 . A rotating shaft 10 with a cantilever structure is provide...

Abstract

Provided are an air stream milling facility which can finely mill a crop like a soybean to a predetermined particle size without occurring thermal denaturation, and a low temperature milling method using the same. The air stream milling facility of the present invention comprises: an air stream mill having two rotor blades (15, 16) rotating at high speed installed inside a casing (9) composed of a cylindrical main body (7) with a taper-shaped front lid (8); a raw material supplier for continuously supplying a raw material from the rear surface of the cylindrical main body; and an absorption device for absorbing and collecting a milled material from the front of the taper-shaped front lid. A cooling means to restrain the milling temperature under 55 DEG C is installed in the casing. The cooling means, for example, is a flow path (26) of cooling water for circulating a coolant.

Description

technical field [0001] The invention relates to an airflow milling equipment suitable for grinding soybeans and other grains and a low-temperature grinding method using the airflow milling equipment. Background technique [0002] For example, in order to manufacture soybean milk for beverages from soybeans, soybeans are pulverized and poured into warm water to elute nutrients such as soybean protein. In order to make the soy milk drink not too powdery and without rough feeling, the soybean must be finely pulverized to a particle size below the specified size. [0003] Conventionally, in order to crush soybeans and other grains, pin mills, hammer mills, axial flow mills, etc. have been generally used. However, with these pulverizers, it is difficult to obtain pulverized products with little coarse powder and a narrow particle size distribution. In addition, with such a grinder, it is almost impossible to finely grind raw soybeans, which contain a large amount of lipids. ...
