Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention applies to dyeing and other treatments using a treatment solution while a fiber material such as cheese is loaded in an image treatment tank.
The present invention relates to a dyeing/drying method and apparatus that can perform dehydration and drying.

2. Description of the Related Art Conventionally, in the treatment of fibrous materials such as cheese, treatment with a treatment liquid such as dyeing and dehydration and drying processes have been carried out using separate treatment apparatuses.

For example, in the case of cheese dyeing, a large number of cheeses loaded in a closed processing tank are piled up via spindles, and processed through a processing liquid circulation path equipped with a pump. Next, the cheese is removed from the processing tank, dehydrated using a centrifugal dehydrator, and dried using a hot air dryer, and operations such as loading, unloading, and loading are repeated for each treatment.

``Problems to be Solved by the Invention'' When loading and unloading are repeated for each process, as in the case of two-legged bicycles, not only is there a time loss, but a large amount of time is required for loading, unloading, and transportation and management during the process. There were some difficulties that required effort.

In order to solve the above-mentioned difficulties, the present invention aims to efficiently carry out operations such as dyeing, dehydration, drying, etc. while being loaded in a treatment tank for dyeing, etc.

Means for Solving the Problems In order to achieve the object of the present invention, a sealed processing tank is used in which the flow path can be changed and the processing liquid circulation path and the hot air circulation path are connected in a switchable manner. A treatment process in which the fiber material is loaded and the treatment liquid in the treatment tank is circulated, a process in which the treatment liquid is discharged from a drainage valve provided in a part of the circulation path, and a process in which the drainage valve is closed and high-pressure air is supplied to the treatment tank. a dehydration process in which the drain valve is suddenly opened to utilize the pressure difference; and a drying process in which hot air is circulated by switching the circulation path connected to the treatment tank. and, respectively, a dyeing and drying treatment method in which the M fiber material such as cheese is carried out while being loaded in the sealed treatment tank, and a switching cock for the closed treatment tank in which the H&male material such as cheese is loaded as a device for realizing the above method. It is possible to change the flow path through the system, and a processing liquid circulation path and a hot air circulation path are provided, and gate valves are provided on the inflow and outflow sides of the processing liquid circulation path and hot air circulation path, respectively. The treatment liquid circulation path is equipped with a water supply valve, a pump, and a drain valve, the hot air circulation path is equipped with a cooler, a blower, and a heater, and the sealed treatment tank is equipped with an air pressure valve. We have provided a dyeing and drying processing equipment comprising:

Function: In the method according to the first aspect of the present invention, the treatment liquid circulation path is first opened and the treatment liquid is forcedly circulated by a pump, while the object to be treated is loaded into the closed treatment tank.
Treatments such as staining are performed. After the treatment, the liquid is drained from a drain valve provided in a part of the treatment liquid circulation path. Next, with the material still loaded, the drain valve is closed and high-pressure air is introduced into the sealed processing tank to increase the internal pressure of the processing tank and maintain it at a constant pressure.
By suddenly opening the liquid drain valve, the internal air pressure is lowered, and the dehydration process is carried out due to the pressure difference between the inside and outside of the object to be treated.Next, the connection is switched from the treated liquid circulation path to the 8-air circulation path. Perform drying with hot air. Meanwhile, in a processing tank where the flow path can be changed, the lPim material such as cheese placed on the carrier may be passed through the processing liquid or hot air from the inside to the outside, or the flow path can be changed from the outside to the inside. This makes it possible to change the processing and drying operations, and by changing the circulation path, it is possible to carry out a series of dyeing, dehydration, and drying operations while the product is still loaded in the closed processing tank.

Next, in the apparatus as the second invention, the introduction and discharge directions of the processing liquid or hot air from the circulation path into the processing tank can be changed by the switching cock, and the inflow and discharge directions of the processing liquid circulation path and the hot air circulation path, respectively, can be changed. There is a gate valve on the outflow side to allow selective connection of the circulation path.

Therefore, it has become possible to selectively utilize the entire cheese dyeing process by changing the flow path using the switching cock and switching the gate valve.

In addition, during dehydration, the process liquid in the process tank is discharged by opening the drain valve in the process liquid circulation path, and the pressure is increased using a pressure valve to temporarily close the drain valve and introduce high-pressure air into the process tank. The dewatering step is carried out using the dewatering effect caused by the pressure difference between the inside and outside of the object to be treated by raising the pressure and suddenly opening the drain valve after maintaining a constant pressure.

During hot air drying, by switching the gate valve so that the hot air circulation path is connected to the processing tank, hot air that has passed through the heater is introduced into the processing tank by the blower, and moist air from the processing tank is directed to the cooler side. After the cooling drain is discharged,
A circulation system is constructed in which the water is introduced from the blower to the processing tank again.

Example The embodiments shown in the drawings will be described below.
