Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] This invention relates to a heating device in a grain humidifier that adds moisture to grains to adjust the moisture content to an appropriate value.

[Conventional technology]

Grain humidifiers are already widely used. However, in cold regions, the outside temperature drops during the winter, so the grains do not absorb the added water. In order to solve this problem, a grain humidity conditioner equipped with a heating device has already been proposed. The structure of this conventional heating device is that several panel-shaped heating elements are installed upright in the tank of a grain humidity conditioner at regular intervals, and the grains that gradually flow down while circulating in the tank are brought into contact with the heating elements. The purpose is to increase grain temperature by applying heat to the grains.

[Problem that the invention seeks to solve]

However, in conventional heating devices, the grains are heated by contacting them with a vertically erected panel-shaped heating element, so the grains flow down while contacting the heating element, and the grains are heated at the poles of the heating element. Grain flowing down close to the heating element is heated, but grain flowing down far away from the heating element is not heated because the heat does not reach it.

This is particularly noticeable since grains have poor thermal conductivity. As a result, there is an uneven heating state in which some of the grains in the tank are heated and some are not, and as they are humidified in this state, there is a difference in the amount of water absorbed between the grains, and the grains are evenly heated. The disadvantage is that it cannot control humidity. In addition, in the past, the temperature was simply adjusted based on the average temperature without realizing that such uneven heating existed, which resulted in the temperature of some grains becoming extremely high, resulting in a loss of flavor. It has become.

The present invention aims to solve these problems and provide a heating device that can uniformly adjust the temperature of all grains in a grain humidity conditioner.

[Failure to solve the problem]

The technical means of the heating device for the grain humidity conditioner of the present invention is to store the grain to be moistened in a substantially sealed tank, and to add moisture to the grain while circulating the grain in the tank. A heating element is installed in the machine at a position where the grains to be moistened pass through while rolling, so that heat is applied evenly to all the grains.

[Effect]

In the present invention, since the grains are heated at the rolling locations, heat is applied equally to all grains, and all grains are evenly heated to an appropriate temperature.

〔Example〕

DESCRIPTION OF THE PREFERRED EMBODIMENTS The heating device for a grain humidity conditioner according to the present invention will be described with reference to the embodiments shown in the drawings. A grain humidity control machine has a grain lifting machine (1) with a set of screws set up in the center of a nearly sealed tank, and circulates by moving the grains at the bottom of the tank to the top with the grain lifting machine (1). At the same time, a mist of moisture is applied to the grains using a sprayer (2) etc. at the top of the tank, and the moisture is allowed to penetrate into the grains as it gradually flows down inside the tank. By repeating this process, the desired moisture content is carefully achieved. It humidifies the air. (3) is a trumpet-shaped extension provided at one end of the grain lifting machine (1); (4)
is a stirring body.

This stirring body (4) is attached to a support member (5) on the rotating shaft of the grain frying machine (1).
), the upper surface of the extended part (3) is rotated as the shaft rotates, and the valves stir the moving grains, and the water sprayed from above is distributed evenly over the surface of the grains. Make sure it sticks to the surface. The stirring body (4) is still connected to the extension part (3).
), the grains rotate in a position with a slight gap between them and the upper surface of the grain (3), and the grains are agitated and form an almost layered structure in the expanded part (3).
It moves up the slope of 2" and falls sequentially from the outer periphery of the upper end. (6) is a cover.

(7) is a heating element which is attached to the lower surface of the extension part (3). The heating element (7) may be an electric heating type, a steam type, or another heating type. Further, the mounting position of the heating body (7) is also arbitrary; for example, it may be mounted on the inner wall of the cover (6) to heat the grains with axial heat.

Heating can be done at any position in the tank as long as all the grains can be heated evenly, but since the grains are stirred in the expansion part (3) to distribute moisture evenly, it is best to heat at this position. It is most preferable to heat the mixture at

〔Effect of the invention〕

The heating device of the grain humidity conditioner of the present invention can apply heat evenly to all the grains during humidity conditioning, and can maintain the grain temperature at an appropriate temperature, so it can be used even in cold regions or in winter. Humidity control work is possible.
