Description

[Detailed description of the invention] (Field of industrial application) The present invention is an improvement of a solid fluid aeration treatment device that applies hot air or cold air aeration treatment to solid fluids, such as coffee beans, cereals, flour, etc. It is related to.

(Prior Art) Conventionally, a solid fluid aeration treatment device transfers solid fluid using a transfer conveyor and aerates the solid fluid by stirring it with hot air or cold air. Although the solid fluid is sprayed toward the solid fluid, the solid fluid remains as a puddle on a portion of the conveyor, resulting in insufficient aeration, making it impossible to achieve uniform aeration. Furthermore, in order to perform sufficient ventilation treatment, if the width of the crosspiece of the transfer conveyor is increased, the length of the crosspiece is lengthened, and the ventilation air blowing time is lengthened, the installation space for the equipment becomes large, the equipment cost increases, and the belt of the transfer conveyor increases. Troubles such as belt meandering and belt breakage are likely to occur during operation. Therefore, daily maintenance and inspection are essential.

(Problem to be solved by the invention) Therefore, in a solid fluid aeration treatment device using a transfer belt, if the aeration air is strongly blown onto the solid fluid on the transfer conveyor, the solid fluid will simply scatter on the transfer conveyor. However, there was a drawback that there was a limit to the effective aeration treatment and uniformity.

(Means for Solving the Problems) The present invention includes a cylindrical rotating drum with an insulating structure that is rotatably supported horizontally via an external power, and a system for introducing a solid fluid for aeration treatment into the rotating drum. A hopper installed at one end of the rotating drum, an outlet for discharging solid fluid after aeration treatment formed at the other end of the horizontally supported rotary drum, and a solid flow for aeration treatment in a natural falling state. an air blowing device that blows air at a preset temperature almost in a curtain shape on a straight line on the bottom of the rotary drum that is perpendicular to the center of rotation of the rotating drum on which the animal falls; and a ventilation air at a preset temperature on the air blowing device. The rotary drum is characterized in that it is provided with a specific temperature aeration air generation and circulation device that sucks in and circulates the aeration air supplied into the rotating drum.

(Function) In the solid fluid aeration treatment apparatus configured as described above, the solid fluid for aeration treatment is introduced into the hopper, and in a state where it flows into the bottom surface of the cylindrical rotating drum, the bottom surface on the vertical line of the rotation center of the rotating drum is introduced. At the same time, solid fluids are scattered by a ventilation device that blows ventilation air at a temperature set in advance by a ventilation air generation circulation device at a specific temperature almost in a curtain shape, and the scattered solid fluids fall naturally to the bottom of the rotating drum. Although it falls, since the drum is rotating, the solid fluid is evenly aerated without forming pools or stagnation, and the solid fluid is transferred and discharged after the aeration treatment according to the slight inclination of the rotating drum. The temperature of the aeration air discharged from the waste outlet and subjected to aeration treatment is set to a specific temperature by an aeration air generation/circulation device that supplies hot air with a positive temperature or cold air with a negative temperature for the purpose of using the solid fluid into the rotating drum.

(Embodiment) Next, the configuration of a first embodiment of the present invention will be described with reference to FIGS. 1 to 3.

A cylindrical rotating drum 1 has a heat-retaining heat insulating material 14 applied to almost the entire circumference of the cylinder, a plurality of ventilation air outlets 3 are opened at one end of the outer circumference of the cylinder, and the bottom of both ends of the outer circumference of the rotating drum 1 is fixed. Two pairs of free rollers 15 attached to the stands 31 and 33 are used to support the cylindrical portion to which the insulation material 14 is not attached horizontally so as to be rotatable, but slightly inclined with the left side facing down in Figure 1 for solid fluid transfer. The rotational power of the rotating drum 1 is driven by an electric motor 17 attached to a fixed base 32, which is transmitted to a pair of chain wheels 20 by a roller chain 19 and driven by a drive pulley 18.
A rotational force is applied to the cylindrical outer periphery of the rotating drum 1 by the frictional force of the drive pulley 18. A hopper 2 is attached to the top of a disk-shaped fixing plate 12 that is attached to a fixing base 31 with a mounting bracket 28 at one end of the rotating drum 1 in order to charge the solid fluid 27 for aeration treatment into the rotating drum 1. The other end of the rotating drum 1 has a sealed structure with a disk-shaped fixing plate 13 attached to a fixing base 33 with a mounting bracket 28. Inside the rotating drum 1, pipe-shaped nozzles 26 are protruded at equal intervals in the circumferential and longitudinal directions of a cylindrical body 5 that rotates in the opposite direction to the rotating drum 1, and both ends protruding outside the rotating drum 1 are fixed. The cylindrical portion is rotatably supported horizontally by two pairs of free rollers 16 attached to the stands 31 and 33, and the rotational power of the cylindrical body 5 is generated by an electric motor 21 attached to the fixed stand 30, The chain wheels 22 and 24 are transmitted by a roller chain 23 to directly apply rotational force to the cylindrical body 5, and furthermore, inside the cylindrical body 5, there are no other nozzles other than the nozzle 26 located perpendicular to the rotation center of the rotary drum 1.

On the other hand, the ventilation air discharge duct 7 is connected to the intake port of the temperature setting device 11 for suction and circulation, thereby forming a specific temperature ventilation generation and circulation device 9.

Next, the operation of this embodiment will be explained.

As shown in FIG.
7 is introduced from the hopper 2 and flows into the bottom surface of the rotary drum 1. When the aeration air is introduced into the bottom surface of the rotary drum 1 on the vertical line of the rotation center of the rotary drum 1, the aeration air at a temperature preset by the specific temperature ventilation generation circulation device 9 is applied to the aeration air blowing device 4. The solid fluid material 27 for aeration treatment is injected from the nozzle 26 and scattered along with the ventilation air, and the scattered solid fluid material falls by gravity onto the bottom surface of the rotating drum 1.
Because it rotates, the solid stream for aeration treatment is uniformly aerated without forming pools or stagnation, and the nozzle 26 in the longitudinal direction repeats scattering and aeration treatment, and the rotating drum 1 repeatedly stirs the solid stream for aeration treatment. While the animals 27 are evenly aerated, they are continuously transferred to the solid fluid discharge port 8 along the slight inclination of the rotating drum 1, and the aerated solid stream is transferred and discharged from the solid fluid discharge port 8. The animal can be ventilated at a temperature of hot air with a positive temperature or cold air with a negative temperature, which is set in advance by the specific temperature ventilation generating/circulating device 9.
