Description

[Detailed explanation of the invention] [Industrial application field] This invention continuously absorbs water into grains,
This invention relates to a device that allows uniform water absorption.

[Conventional technology]

Conventionally, in the raw material processing process for grains such as rice for sake brewing or other foods such as polished rice, green rice, barley, and buckwheat, soaking tanks have been used as a means to make the grains absorb water. The grains are soaked in water and soaked in water, or the grains are placed in a water-filled tank and soaked for water absorption. If it takes longer than that, excess water will result.

[The problem that the idea attempts to solve]

The shorter the immersion water absorption period, the greater the difference in the amount of water absorbed by the raw material between the top and bottom of the tank, or between the beginning and end of charging.

These uneven moisture contents of raw materials cause a great deal of trouble in subsequent processes, leading to a decline in product quality and a decrease in raw material utilization.

[Means to solve the problem]

Here, this invention is based on a dipping process A in which the raw grain is immersed in water on the upper endless transport means U of the endless transport means U and L that are folded in two stages, upper and lower, in the device main body 1. and a draining process B to remove excess moisture, and on the lower endless transport means L, a water absorption process C is carried out to uniformly infiltrate the raw material grain with moisture.
A hopper 8 equipped with a level meter 10 for controlling the amount of grain supplied in the soaking process A, a stacking thickness adjustment damper 12 connected to the hopper 8, and an endless type of transportation above the hopper 8 and after the adjustment damper 12. a shower device 13 on the means U;
And, during the subsequent transition from the draining step B on the endless transport means U in the upper tier to the water absorption step C on the endless transport means L in the lower tier, continuous immersion is performed to turn over the piled layer of grains. This paper proposes a water absorption device.

[Effect]

In the above-mentioned immersion water absorption treatment for grains that have a high water absorption rate, it is extremely difficult to achieve uniform water absorption using the conventional batch-type water absorption means using an immersion tank. The endless transport means for this purpose is made up of two upper and lower folded tiers, with the grain turned upside down when moving from the upper tier to the lower tier, and by providing the same water absorption conditions to each particle of the grain. This is designed to ensure uniform water absorption and constant moisture content. In addition, in order to treat not only one type of grain but also many types of water absorption conditions,
The structure allows for a wide range of adjustment of the moisture content of the raw material after water absorption.

〔Example〕

Next, this invention will be explained with reference to illustrated embodiments.

Inside the main body 1 of the continuous immersion water absorption device, there are two pairs of rollers 2, 2, 2', and 2' arranged in upper and lower stages. The endless belts 3, 3' having the above are strung together to constitute an upper endless transport means U and a lower endless transport means L. 4, 5, 6, 7 are receivers for excess moisture supplied to the grains, 8 is a receiver hopper for the grains 9,
A level meter 10 is installed in the hopper 8, and the grain supply and transportation device is controlled by the upper limit control instruction of the level meter 10. 11 is a transport pipe for the grains 9, which is connected to a liquid or gas transport device (not shown).

12 is a damper for adjusting the pile thickness provided at the outlet of the receiving hopper 8; 13 is a shower device that supplies moisture to the grains; 14 is a water temperature adjustment device for uniformly absorbing moisture into the grains; 15 is an immersion water absorption device. This is the outlet for processed grains.

Grain 9 sent from the transport device through a transport pipe 11 is supplied to a receiving hopper 8 and is deposited in this receiving hopper 8, the height of which is controlled by a level meter 10. When the grain level reaches the upper limit, the level meter 10 controls the transportation to stop, thereby keeping the grain thickness in the receiving hopper 8 constant. Also, by adjusting this deposition thickness, the receiving hopper 8
In the case of water transportation, the contact time between the grain and water, that is, the soaking time, is adjusted.

When grains are transported in dry form depending on the type of transportation, water is sprinkled by the shower device 13 above the receiving hopper 8 to create a water absorption environment.

The upper endless transport means U is supplied from the receiving hopper 8 and adjusted to the deposition thickness by the damper 12.
The grains on the endless belt 3 are supplied with water by the shower device 13 with cold water or hot water adjusted to an appropriate temperature by the water temperature adjustment device 14 that creates uniform water absorption conditions, and the grains are made to absorb water. The steps up to this point are dipping step A.

In this case, the water absorption amount is adjusted by increasing or decreasing the number of shower stages. In addition, the excess water from the shower passes through the grain sediment layer, and the water with high turbidity that is received by the former stage receivers 4 and 5 provided at the bottom of the endless belt 3 is discarded as is, and the latter stage receivers 6 and 7 are disposed of. Those with low turbidity, such as, are recycled. However, if the washing in the pretreatment stage is good and the turbidity is low, there is no need for divisions such as receivers 4, 5, 6, and 7.

In this way, the piled layer of grains travels on the endless belt 3 of the upper endless transport means U, is drained in the draining step B, and is drained in the endless belt 3 of the lower endless transport means L, forming the water absorption step C. The water is deposited on the belt 3', but in this case the deposited layer is turned upside down, so that water absorption conditions can be made uniform.

The length and width of the endless belt constituting the device are arbitrarily selected depending on the immersion and water absorption processing capabilities. Further, the traveling speed of the endless belts 3, 3' can be adjusted arbitrarily to adjust the amount of water absorbed and the processing capacity, respectively.

In addition, in the above structure, an intermediate crusher 16, which is a conventional means, may be installed at key points on the endless belts 3, 3' to make the water absorption as uniform as possible, if necessary. If the grain solidifies after completion of treatment due to its properties, a crushing device 17, which is also a conventional means, may be provided at the outlet to separate the bound grain particles and send them to the next step.

[Effect of idea]

As mentioned above, the device of this invention is capable of adjusting the height of grain piled in the receiving hopper and the thickness of grain piled on the endless belt, adjusting the damper, adjusting the number of shower stages of the shower device, adjusting the temperature of the shower water using the water temperature control device, and controlling the grain pile height on the endless belt. By adjusting the speed of the belt, etc., it is possible to continuously and arbitrarily adjust the water content according to the degree of water absorption of the grains, and it is also suitable for transitioning from the upper tier endless transportation means to the lower tier endless transportation means. By reversing the top and bottom of the sedimentary layer of grains, water absorption conditions for the grains can be made uniform.
