Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a rice steaming apparatus for sake brewing. Conventional rice steamer RK has a net conveyor (net bell) (A steam jet pipe (q) is placed in the middle between Bl to block the steam from the net conveyor (the above steam jet pipe FC is above Al) A cover tU is installed, and the cover (DJ has steam exhaust ports 1h on the front and back
A hopper (F) is provided on the cover (I) at a position in front of the conveyor 4, so that washed rice can be freely input.

In the case of this rice steaming device, the steam temperature on the net conveyor (4) is maintained at around 100C under atmospheric pressure, so the steam flow rate ejected from the steam jet pipe (C1) must be higher temperature and pressure.

In such a case, open the front and rear openings (from 01 onwards, a large amount of steam will be ejected from the cover) (steam outlet on the front and rear of the uniform)!X1
111 is installed for forced exhaust. However, because this device requires steam to be ejected under high pressure, the ejected steam is directly exhausted from the outlet (GL11), which causes temperature unevenness and makes it impossible to equalize the steamed rice. At the same time, heat loss is large, and in order to maintain the ideal temperature (100C or higher), a large amount of steam must be discharged from the exhaust port, which is wasteful.

The present invention was researched to solve the above-mentioned drawbacks of conventional rice steaming equipment, and it maintains the temperature inside the airtight cover at 98C to 103C using extremely low pressure steam under atmospheric pressure to achieve even steaming without temperature unevenness. The present invention aims to provide an extremely economical rice steaming apparatus that can pressurize steamed rice continuously and effectively use heat to reduce heat loss.

To describe the uninvented invention in detail with reference to the illustrated embodiment, a net belt (1) is wound around a drum (2) (25) and a net conveyor (3) is driven at a slow speed. The net conveyor (3) and the supply conveyor (4) are open to atmospheric pressure at the bottom (5), and the top is covered with an airtight cover (51') made of a heat insulating material. In step 5), the airtight cover (5) is covered to a depth that covers at least the net conveyor (3), but by making the airtight cover (5) deeper, steam is prevented from blowing out even if the temperature is adjusted.

There is a sparge pipe in the middle position of the net conveyor (3).
y (6) (65...) to freely supply extremely low pressure steam using pressure reducing valves, temperature control valves, etc., and the sparge vibrator (6) (6 A heating heater (7) (75...) using a steam heater pipe is arranged above the D-... so that heating can be performed freely, and the heating heater (7) C75... is heated by the equal pressure of the temperature control valve. The temperature inside the airtight cover (5) can be adjusted freely, and a drain receiver (8) is provided at the lower part of the chevron-shaped slope (51') of the airtight cover (5) to allow draining. 5), soil partition plates (9) (t+5...) made of stainless steel are installed at predetermined intervals in the traveling direction of the net conveyor (3), and the upper partition plates (9) (95... A lower partition plate IIQI (selection...) is provided which is made of silicone and has good heat resistance and peelability.At this time, the lower end of the lower partition plate (10) CI (1...) is through which the steamed rice on the net conveyor (3) passes. It is kept at a high height and brought into close contact with the steamed rice on the net conveyor (3) to weaken the flow of steam and to equalize the temperature of the required amount fσ.

In addition, heating heater (7) (75... is the net conveyor (3) C1,) may be installed only at the rear position (discharge side) from the middle, and the front (supply side) K may not be installed, or the heater at the rear position Heating heater (7) (75... may be made hotter than the heating heater (7) <75... at the front position.

This is because when you press the button to steam rice, you can get better steamed rice by using low heat at the beginning and then using strong heat afterwards.

In the figure, the receiver (11) is a plate that receives drains, rice, etc. that fall from the net conveyor (3). H(11...
・ is a partition plate of the supply conveyor (4). αQ is the upper alignment plate. ■ is the heat insulating layer of the airtight cover (5).

The present invention is realized as described above, and in order to use it, it is necessary to connect the boiler (not shown) to the steam separator, pressure reducing valve, etc. The steam is pumped out and the pressure is reduced to a flow rate of 2 to 3.1 cm per second (approximately 0.0 cm in gauge pressure kg/cdto).
005) to supply air and heat the heater (7) (
75... maintains the inside of the airtight cover (5) at an ideal steamed rice temperature of about 103 tons, and supplies the required amount of washed rice from the supply conveyor (41) to the supply side of the net conveyor (3).

In this way, by rotating the net conveyor (3) at a slow speed (about 1 hour on the outward trip), the washed rice is aligned on the upper leveling plate 0□□
It is steamed to a uniform thickness by □, and is discharged from c to the discharge side: if1.

The present invention utilizes a net conveyor that allows rice to be freely supplied as described above, the lower part of which is open to atmospheric pressure, and the upper part of which has a chevron-shaped or inclined shape.
It is covered with an airtight cover that has a flat surface, and inside the airtight cover, it is possible to freely supply steam at extremely low pressure. The atmosphere inside the cover is pushed by the atmospheric pressure that is opened at the bottom, so it does not leak to the outside, and it is heated evenly, so there is no temperature unevenness, and the atmosphere inside the cover is slightly heated by the steam. <
