Abstract

PURPOSE:To contrive to energy in the production of feather meal, by using an apparatus composed of a nearly cylindrical outer case furnished with a compression dehydration zone and a high-temperature heating zone and a hollow rotary shaft having screw blade at the outer circumference and treating raw feather with the apparatus. CONSTITUTION:A hollow rotary shaft 4 having screw blade 5 at the outer circumference is inserted into a nearly cylindrical outer case 3. The outer case 3 is furnished with a compression dehydration zone 6 having a number of liquid- leaking perforations 8 and a high-temperature heating zone 7 surrounded by a steam jacket 9. The zones 6 and 7 are placed in the order. The hollow rotary shaft 4 is expanded gradually toward the transfer direction and the raw feather supplied as a raw material is pressed between the shaft 4 and the outer case 3 according to the rotation of the shaft 4. Excess water is squeezed out by this process. The raw feather is then heated with hot steam introduced into the steam jacket 9 and the hollow rotary shaft 4.

Description

DETAILED DESCRIPTION OF THE INVENTION (a) Field of Industrial Application This invention relates to an apparatus for producing feather meal, etc.

(b) Conventional technology Feather meal has traditionally been made from broiler feathers that have been pickled in lagoons and depilated, first steamed at normal pressure to soften the feathers, and then heated at high temperatures to remove the hard particles in the feathers. Feather meal was produced by hydrolyzing protein to increase its digestibility and finally drying it.

(c) Problems to be solved by the invention However, feathers steamed at normal pressure contain excessive moisture, and during the next high-temperature heat treatment, the feathers are heated to excess moisture.
Furthermore, there is a drawback that excessive water is evaporated during the drying process, resulting in a large amount of energy consumption such as fuel.

(d) Means for solving the problem In this invention, a hollow rotating shaft having screw blades arranged on the outer circumferential surface is inserted into a substantially cylindrical outer case, and a large number of liquid leakage holes are provided in the outer case. A perforated compression dewatering section and a high-temperature heating section whose outer peripheral surface is surrounded by a steam jacket are provided, or each section is arranged in succession in the above order, and
The diameter of the hollow rotating shaft is gradually expanded in the conveying direction, and the raw material feathers interposed between the coaxial and the outer case are compressed by the rotation of the coaxial, and then the raw feathers of the raw material interposed between the coaxial and the outer case are compressed, and then the high steam inserted into the steam jacket and the intermediate rotating shaft is compressed. It is an object of the present invention to provide an apparatus for producing feather meal, etc., which is configured to heat raw feathers to a high temperature.

(E) Function In this invention, the raw feather raw material is conveyed through the outer case by the rotation of the hollow rotating shaft, and the raw feather is compressed by expanding the diameter of the hollow rotating shaft, and the moisture in the raw feather is removed in the compression dewatering section. At the same time as squeezing, the same feathers are kneaded and compacted, and then in a high-temperature heating section, the compacted raw feathers are subjected to high-temperature heat treatment using high-temperature steam inserted through a steam wicket and a hollow rotating shaft to produce raw feathers. The hard protein inside is hydrolyzed to produce highly digestible feather meal.

(f) Effects According to the present invention, excess moisture is squeezed out from the raw feathers prior to high-temperature heating, so there is no need to heat the excess moisture, so less energy is required for heating, and During the drying process, less water evaporates, resulting in less energy consumption.

(G) Embodiment The embodiment of the present invention will be described in detail based on the drawings. (A) shows an apparatus for producing feather meal, etc., with a raw material supply port (1)
A substantially cylindrical outer case (
3) was hung horizontally, the raw material supply port (1) was opened upward, the product discharge port (2) was opened upward, and the diameter was gradually expanded in the direction of the product discharge port (2) into the outer case (3). A hollow rotating shaft (4) is inserted into the shaft, and a screw blade (5
) are arranged in a state surrounding the coaxial shaft (4), and the raw material feathers input from the raw material supply port (1) are conveyed to the product discharge port (2) by the rotation of the coaxial shaft (4). There is.

The outer case (3) has a compression dehydration section (6) and a high temperature heating section (
7) are repeatedly arranged alternately, and the press dewatering section (6
) has a large number of micro-diameter liquid leakage holes (8) drilled in the wall of the outer case (3), and excess moisture is squeezed out from the compressed raw feathers by expanding the diameter of the hollow rotating shaft (4). The high-temperature heating section (7) consists of a hollow rotating shaft (4) and a steam jacket (9) surrounding the outer periphery of the outer case (3) of the high-temperature heating section (7). It is configured to heat-process raw feathers in a compressed state using steam at a high temperature while they are being transported. In addition, a pressure adjustment mechanism (10) is connected to the end surface of the product discharge D (2> side of the outer case (3), and the mechanism (10) biases a ring-shaped pressure adjustment y4 (11). Crimp the end face of the outer case (3) with the mechanism (12),
By adjusting the biasing force of the biasing mechanism (12), the outer case (3
) to adjust the internal pressure.

In the figure, (13) is an interlocking mechanism for driving the hollow rotating shaft (4), (14) is a pressure adjustment ring, and (14) is a pressure adjustment ring.
4) is for adjusting the pressure distribution inside the outer case (3).

Then, the raw material raw feathers fed into the raw material supply port (1) are gradually transferred to the product discharge port (2) by the rotation of the hollow rotating shaft (4).
) direction, the feathers are gradually compressed by expanding the diameter of the coaxial shaft (4), and excess moisture is squeezed out from the liquid leakage hole (8) of the compression/dehydration section (6). In section (7), hard proteins are hydrolyzed and are turned into highly digestible feather meal which is discharged from the product outlet (2) to the outside of the machine.

The product feather meal discharged from the product outlet (2) has a water content of 1835%, which is lower than that of conventional methods, and requires less energy for drying. As a result, less water is heated and less energy is required for heating, resulting in energy savings. In addition to the raw material raw feathers, bones etc. can be used alone or in combination with the raw feathers.
