In transportation, the exhaust vent 3 is opened, the remaining ammonia gas is exhausted, and the transporting door 1 is opened, to transfer the feed.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an apparatus for ammonia processing roughage such as reeds, rice straw, or wheat straw.

Conventionally, there has been known a method of producing feed that increases the value of feed through strong alkali treatment, as disclosed in Japanese Patent Publication No. 56-10016 by the same applicant. There was a bribe while the scaling was done without a meeting.

Therefore, the purpose of the present application is to obtain the same reaction effects as this soda treatment method, and to provide an ammonia treatment device that is a simple treatment device that can be used for individual farmers. The feature is that it takes advantage of the strong diffusivity and sterilizing effect of ammonia, and an ammonia distributor is placed in the lower layer of the mounting part to form a reaction chamber, and an exhaust hole is formed in the upper wall of this reaction chamber. The present invention is characterized in that the ammonia treatment apparatus is constructed by providing an ammonia concentration detection means on the minus side.

The configuration will be described below based on the drawings in which the present invention is implemented.

Figure @1 explains the reaction process of ammonia.

0 is loaded and moved, and a carry-out conveyor 6 is provided on the carry-out side. Reference numerals 7 and 8 each indicate electric motors for the conveyor 5.
, drives the delivery conveyor 6. Reference numeral 20 denotes a buried vent, which is installed in the earthen wall of the reaction chamber a, and is connected by a duct 21 to several ventilation holes bored in the floor plate of the reaction chamber a. Reference numeral 3 denotes an exhaust hole, which is provided above the W-ring fan 20 and has a damper 9, so that it can be opened and closed. b shows the ammonia supply device, measuring machine 1
A gas cylinder 15 is mounted on the chamber 4, and this cylinder 15 is connected via a valve 17 to a distribution pipe 16 disposed close to the floor plate 11 of the reaction chamber a.

13 is a control panel connected to the above-mentioned measuring device 14, and when a predetermined gas supply amount is dialed, ammonia gas is supplied through a valve 17, while the ammonia gas detection rod 12 is connected to the control panel 13. and control panel 13 shows reaction chamber a.
This is to detect and display the degree of condensation within.

3 to 5 show the structure of the reaction chamber a, which is rectangular in plan view, with a conveyor 5 that also serves as a loading section for the raw material 10 installed horizontally at the bottom, and a drive shaft 18 driven by an electric motor 7. Drive with more power. Reference numeral 6 is a carry-out conveyor, which is divided into left and right sides, has a band shape, and is operated with a drive shaft 19 installed at the front end, and the other end is disposed overlappingly on the outside of the conveyor 5 described above. The discharge n1 is opened and closed by a hydraulic cylinder 11, and is electrically connected to the damper 9 of the exhaust hole 3, although not shown.

Next, the working process will be explained based on FIG. 6.

(1) Weighing work and loading 1, U crude raw materials 10, which are pasture, rice straw, or piled straw, are weighed and transported to reaction chamber a by a front lobe, etc.
2 is opened and loaded, and at this time, the conveyor 5 is used appropriately to move and stack the items.

(2) Ammonia supply 2~
4% ammonia gas is supplied and added, and when a dial that converts the weight and percentage in advance is set on the control panel 13, it is automatically added using the valve 17.

(3) After being left to react and being fed, ammonia is added while generating heat.
It dissolves in the water, reacts violently with the material components, and gradually becomes weaker.

This device uses half-dried rice straw material with a moisture content of 30 cm and lasts about 10 days at room temperature in summer.

Since ammonia gas is highly volatile and has a tendency to accumulate in the upper layer of the reaction chamber a, the circulation fan 20 is operated about once a day to measure the diffusion of the ammonia vaporized air, and to check the overall uniformity of the raw materials and the reaction time. promote During this reaction process, ammonia remains in the pit as a liquid. The gas concentration in the reaction chamber a is detected by the detection rod 12 and the control panel 1
It can be monitored and accurately grasped using the detection display in step 3.

(4) Carrying out work Before carrying out, the internal acidity is confirmed on the detection display, and the exhaust hole 3 is opened to discharge the residual ammonia gas, and then the carrying out n1 is opened. Next, the discharge conveyor 6 is operated to carry out the raw material. When the raw material 10 on the side of the carry-out door 1 becomes less, the conveyor 5 is driven to move the entire remaining raw material, so that continuous carry-out can be performed according to instructions from the control panel 13.

In the present invention, since ammonia dissolves in the moisture of the raw material and generates heat due to the reaction, it is best to use half-dried raw materials with a moisture content of around 30% rather than ordinary dry raw materials.

At this time, it also has a drying effect by removing moisture from the raw materials.

If it is later processed in the dry state using this device, it increases the digestibility and at the same time promotes the drying effect, and furthermore, the bactericidal properties of ammonia convert it into a storable feed.

In addition, the upper gas air and lower layer of the reaction chamber are forcedly circulated to speed up the reaction time and produce feed of uniform quality, and the continuous reaction status can be ascertained by the gas level detector, so it can be used in conjunction with the exhaust hole. Therefore, the danger to the human body due to residual ammonia can be eliminated in advance.
