Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to grain packaging apparatuses, particularly those for packaging rice after milling.

Structure of conventional example and its problems If the moisture content of grain is high, it is likely to deteriorate, and if the moisture content is low, cracks will occur. Particularly in the case of rice, the taste of glue deteriorates when the water content is high or low, so the rice glue is adjusted to 14.5% and packed in bags with storage considerations in mind.

Figure 1 shows the conventional bagging process in a rice milling factory. (
1) is a moisture adjustment section, which humidifies rice (B) that has been brought in and has been completely treated to 14.5% moisture by spraying the rice with unadjusted moisture and releases the rice (B). (2) is a storage hopper that receives the fully moistened rice (B), and (3) is a packaging machine that packs the fully moisturized rice (B) discharged from the storage hopper (2) into bags in predetermined amounts. Hopper (2
) to the cut gate (4). (5) represents a sealed bag filled with completely moisture-adjusted rice CB+ by the packaging machine (3).

In this way, conventionally, since the rice (B) with fully adjusted moisture content is packed into bags, the moisture adjustment section (1) repeatedly performs drying and humidification processes until the rice reaches 14.5%. Currently, it takes too much time for the imported rice (3) whose moisture content has not been adjusted to pass through the moisture adjustment section (1), causing a decrease in bagging efficiency.

OBJECTS OF THE INVENTION The present invention provides a grain packaging device that can pass through a moisture adjustment section (1) in a short time to improve the efficiency of packaging such as bagging, and can supply grain with a target moisture value. With the goal.

Structure of the Invention The grain packaging apparatus of the present invention includes a first storage tank that stores grain with a moisture value higher than the final target moisture value, and a second storage tank that stores grain with a moisture value lower than the final target moisture value. a storage tank;
1st. The first step is to detect the moisture value of the cut grains in the second storage tank. a second sensor; a first sensor; A packaging machine that seals the grain cut from the second storage tank in one package is provided, and the amount of grain cut from one of the first and second storage tanks and its moisture value 2 are provided. and the moisture value of the cut grains from the other storage tank, and control and set the cut amount of the other storage tank so that the average moisture value of the total cut grains cut from both storage tanks approaches the final target moisture value. It is characterized by being provided with a control section that instructs packing by weight.

In addition, in the present invention, when items with high moisture content and items with low moisture content are sealed and stored in one package, the items with low moisture content absorb moisture from the items with high moisture content, and after several hours to several days, the entire product has an average moisture content. Based on the characteristic of grains that they settle down to a certain value, this product improves packaging efficiency by simplifying moisture adjustment in the previous process and packaging grains at set weights to ultimately reach the target moisture value. It is.

DESCRIPTION OF THE EMBODIMENTS An embodiment of the grain packaging apparatus of the present invention will be described below with reference to FIGS. 2 and 3. αO is a moisture adjustment unit that is configured to adjust the unadjusted half-time of moisture brought in to a moisture value within the range of around 14% to around 15%, including the final target moisture value of 14.5%, and then release it. The drying means and humidifying means are the same as conventional ones.

αD is the moisture adjustment part (C) released from the moisture adjustment part σO
It is a moisture sorting device that sorts and discharges water into the first group (I) to the third group according to the moisture value, and the moisture content in the moisture adjustment section (C) is equal to 14.5% of the final target moisture value. Those who are in the first group (
Group I), and those with moisture content lower than 14.5% are classified into Group 2 (II).
), those with a moisture content higher than 14.5% are discharged separately to the third group side. (2) (13u4) is the first group (I) ~
The storage tanks 09αG each receive the grains of the third group (2) separately. In the second packaging machine, the first packaging machine (to) instructs the cut gate αη of the storage tank (2) to cut out a set amount of grain, packs the cut grains into bags (to), and packs the cut grains into bags (to). The packaging machine αG controls the cut gate (to) of the storage tank day α4 via the control unit 119 (instructs 2υ to cut and cuts both storage tanks α3q4).
The structure is such that only the grains cut from the grain are packed into the same bag. (c) @ is the first and second moisture sensor, and
In the case of a capacitive type, the electrode portions are arranged near the bottom of each storage tank CL3α4.

The bagging process of grains in the first group t11 is the same as the conventional one, so a detailed explanation will be omitted.
The process of bagging grains in the second group (m and third group) by the second packaging machine tS will be described in detail.

As shown in FIG. 3, the control unit αl controls the microcomputer (to) the first. It consists of a second register wire (a) and the like.

When executing the operation, the first. Second moisture sensor (to) (c)

When N=0 is detected in 3'l, (a-1) (a2)
Execute the 1st step again. The second register (7) is updated and cutting continues. When a quantitative signal from the second packaging machine qe is detected during cutting (a-4), OCkg/5er-) is set on the first and second registers (7) and both storage tanks (13, Stop cutting out from 04 (a-6). When the sealing work of the bag in the second packaging machine U is completed and the setting of the next bag is completed, the cutting from the second packaging machine (1υ) is stopped. The start signal is detected at (a-!'l) and (a-()
) and the bagging work resumes.

Here, the control of the cutting capacity of the cut gate 21> will be explained using a specific example of bagging 1009 rice. In addition, in the following explanation, the final target moisture value is 14.5%.

The storage tank d'a (14) is cut out by setting 15 icg/IIec in the register.

In this way, the extraction capability of the second register @ is controlled. When it is detected in (a-4) that the total cutting amount has reached 1004, cutting is stopped and the opening of the bag is sealed. Bagged items are group 2 (II), which do not reach the final target moisture value of 14.5% immediately after bagging.
However, after several hours to several days have passed in this sealed state, the rice from the second group and the rice from the third group are mixed together.
The #(II) grains absorb moisture from the grains in the third group 0fD, and the grains in the third group (2) release moisture, resulting in a total bias equal to 14.5% of the final target moisture value. Settle for no grains.

In the example, the cutting capacity was cut out from storage tank u3 on the low moisture side at a constant cutting capacity, and the cutting capacity of the storage tank 0 station on the high moisture side was controlled. The same holds true when controlling the moisture side.

As described in the detailed description of the invention, the grain packaging apparatus of the present invention includes a first storage tank that stores grain with a moisture value higher than a maximum target moisture value, and a first storage tank that stores grain with a moisture value lower than a final target moisture value (direct grain). a second storage tank for storing grains cut from the first and second storage tanks; a second sensor for detecting the moisture value of the grains cut from the first and second storage tanks; □ If a packaging machine is installed that seals the liquid in one package, the following information will be provided: 1. The amount of water cut out from one of the second storage tanks, its moisture content, and the value from the other storage tank. Based on the moisture value of the cut grains, the cut amount of the other storage tank is controlled to approach the final target moisture value by the set weight of 7N6. Since it is equipped with a control unit that instructs packing, it is possible to pack grains that have not been completely adjusted to the final target moisture value into bags, etc., omitting or shortening the moisture adjustment process, and increasing the efficiency of the packaging process. It is.
