Problems solved by technology

[0002] The extruders in the prior art are generally open-type pots with stirring devices. If it falls into the processed grain, it will affect the quality of the product. The stirring device will be directly heated for a long time and cycled in the state of heating-cooling-heating-cooling, which will reduce its service life. Peeling occurs, and it is difficult to prevent the peeled oxide layer from entering the puffed grain, affecting the quality of the product, and even leading to waste of processed grain. Open processing, low degree of automation, it is difficult to guarantee the quality of processed grain

Embodiment 2

[0026] Adopt equipment of the present invention to prepare the method for puffed glutinous rice, comprise the steps:

[0027] (1) Pass air into the sealed material box 1 and heat it to a temperature of 220°C, and keep the hot air circulation inside;

[0028] (2) Send the glutinous rice into the sealed material box 1 through the feeding funnel 7;

[0029] (3) The sealed material box is rotated to keep the temperature of the hot air inside it stable, and to ensure a stable pressure of 0.015mpa, and the rotation time is 3 hours; the amount of air introduced into the sealed material box is 4000 m per hour 3 .

[0030] The working process of the grain puffing machine is the same as that of embodiment 1.

Embodiment 3

[0032] The method for preparing puffed corn flakes by using the equipment of the present invention comprises the following steps:

[0033] (1) Pass air into the sealed material box 1 and heat it to a temperature of 200°C, and keep the hot air circulation inside;

[0034] (2) Send the corn flakes into the sealed material box 1 through the feeding funnel 7;

[0035] (3) The sealed material box 1 rotates to keep the temperature of the hot air inside it stable, and to ensure a stable pressure of 0.015mpa, and the rotation time is 3 hours; the amount of air introduced into the sealed material box 1 is 4000 m per hour 3 .

[0036] The puffing working process of the grain puffing machine is the same as that of embodiment 1.

Abstract

The invention discloses a grain puffing machine and a method for preparing puffed grain. The machine comprises a horizontal sealing material box, a blower, an air pipe and a high-temperature converter, wherein one end of the blower is connected with the high-temperature converter through the air pipe, and the other end is connected with a rotary motor through the air pipe; the other end of the high-temperature converter penetrates through the air pipe of the sealing material box and is connected with the rotary motor; and a charging device is arranged at the air pipe on the outer side of one end of the sealing material box. The method for preparing puffed grain comprises the following steps of: (1) heating the air led into the sealing material box to 170-220 DEG C, and keeping hot air circulation therein; (2) feeding the grain into a material barrel through the charging device; and (3) rotating the sealing material box. By adopting the technical scheme of the invention, the floating dust and floating matters in the air are prevented from falling into the product, thus the cleanness of the processed grain is guaranteed, and the quality of the processed grain is further guaranteed.

Description

technical field [0001] The invention relates to the field of food processing, in particular to a grain puffing machine and a method for preparing puffed grains. Background technique [0002] Existing extruders are generally open-type pots with stirring devices. This kind of extruding equipment has a low heat utilization rate. The floating and floating objects in the open processing air will fall into the processed grains, which will affect the quality of the product. The stirring device will last for a long time. Direct heating and circulation in the state of heating-cooling-heating-cooling will reduce its service life, and the metal materials used in the pot body and stirring device will peel off after aging, and it is difficult to avoid the peeled oxide layer from entering the puffed grain , affect the quality of the product, and even lead to the waste of processed food, open processing, low degree of automation, it is difficult to guarantee the quality of processed food....
