Abstract

------10/10/2018------(OCR) Page 1 of 1 Summary of Invention This invention relates to a feeding device that can reduce the pulsation of food objects in the outlet flow path when a disc-type pump used to dispense food objects in the outlet flow path, such as jam, steamed beans, or ground beans, continuously supplies the food object in the outlet flow path. In addition, this invention relates to providing a machine for extruding and forming two-layer stick-like food objects and a machine for covering ground beans, whereby the machine uses a feeding device. This feeding device comprises a disc-type pump that supplies the food object to the outlet flow path, and a controller that controls the disc-type pump. Since the decrease in pulsation of food objects in the outlet flow path is compensated for by periodically controlling the rotation rate of the disc-type pump, it is possible to reduce the pulsation of food objects. Consequently, It is possible to suppress the pulsation flow of bi-layer, rod-like food materials continuously extruded from a dual nozzle in contact with the outlet flow path, and thereby reduce the weight variation of the encapsulated food product which has been sorted from the bi-layer, rod-like food materials by the sorting machine. ------------ The present invention relates to a feeding apparatus which can reduce the generation of pressure pulses of the food material in the outlet flow path when a disc pump used to supply the outlet flow path with food material, such as steamed bean jam bread or crushed beans, continuously supplies the outer flow path with the food material. Furthermore, the present invention relates to providing a machine for extruding and forming bi-layer, rod-like food materials and a machine for encapsulating crushed beans, whereby the machine uses a feeding apparatus. The feeding apparatus comprises a disc pump to supply the food material to the outlet flow path, and a controller to control the disc pump. As the pressure drop of the food material in the outlet flow path is compensated for by periodically controlling the rotation rate of the disc pump, it is possible to reduce the generation of pressure pulses of the food material. Consequently, It is possible to suppress the pulsating flow of the bi-layered, rod-like food material which is continuously extruded from the dual nozzles which are connected to the external flow path and to reduce the weight variation of the encapsulated food product which is cut from the bi-layered, rod-like food material by the cutter.

Claims (14)

------10/10/2561------(OCR) Page 1 of 1 page. Claims: 1. A method for continuously feeding material stored in a feeding hopper to the outlet flow by a bladed pump, incorporating a procedure to control the rotor rotation speed of the bladed pump so that the rate can be switched between a base rate of rotation and a higher rate of rotation. While each of the multiple blades arranged on the rotor at evenly spaced intervals moves to deliver material to the outlet flow, the switching of the rotor rotation speed is repeated corresponding to the rotation position of each blade. 2. A material feeding device consisting of a bladed pump to deliver material to the outlet flow and a control unit to control the bladed pump. The control unit is equipped with a detecting apparatus to measure the rotor rotation angle of the bladed pump. The controller regulates the rotor rotation speed of the bladed pump, allowing for switching between the base rotation speed and higher rotation speeds. Each of the multiple blades, arranged at uniform intervals on the rotor's circumference, moves to distribute feed towards the outlet flow, and the rotor rotation speed is adjusted to match the rotation position of each individual blade. 1. The method for continuously feeding material stored in the feed hopper to the outlet flow path using a vane pump incorporates a mechanism to control the rotation speed of the vane pump rotor, allowing this speed to be switched between a base rotation speed and a higher rotation speed. Each of the multiple vanes arranged at evenly spaced intervals around the rotor moves to deliver material to the outlet flow path. This switching of rotor rotation speed is repeated corresponding to the set position of each vane's rotation. 2. The feeding mechanism consists of a vane pump to deliver the material to the outlet flow path and a control unit to operate this vane pump. This control unit is equipped with a sensor to detect the rotation angle of the vane pump rotor. The control unit regulates the rotation speed of the vane pump rotor so that it can be switched between the base rotation speed and higher rotation speeds. As the vanes, arranged at uniform intervals on the rotor's circumference, move to deliver the material to the outlet flow path, the rotation speed switching is repeated corresponding to the rotation position of each vane. 3. A device under claim 2 which can adjust the timing of the rotational speed switching from the base rate to a higher rotational rate (timing of the acceleration start of the rotation). 4. The method for continuously feeding the stored feed material from the feed hopper to the outlet flow path is performed by a vane pump located at the bottom of this feed hopper. The process for transferring the stored feed material to the vane pump is achieved by rotating transfer rollers located on the side of this vane pump. 5. The device for continuously feeding the stored material from the feed hopper to the outlet flow path is integrated with a plate pump located at the bottom of this feed hopper. The transfer of the stored material from the feed hopper to the plate pump is achieved by rotating transfer rollers located on the sides of the plate pump. 6. A continuous extrusion machine for forming two-layer food products into rod-shaped structures. These two-layer food products consist of two layers: an inner layer encased in an outer layer. The outer feeding machine has a hopper to receive the outer layer and a bladed pump for the outer layer located at the bottom of the hopper. The inner feeding machine has a hopper to receive the inner layer and a bladed pump for the inner layer located at the bottom of the hopper. A dual nozzle system is connected to the inner and outer feeding machines to extrude the two-layer food products into rod-shaped structures by encasing the inner layer. The bladed pumps for the outer and inner layers are arranged so that one bladed pump's axis is vertically aligned and the other's axis is horizontally aligned. 7. The device pursuant to claim paragraph 6, in which the impeller pumps for the outer and inner food components are arranged such that the axis of rotation of the impeller pump for the outer food component is aligned horizontally and the axis of rotation of the impeller pump for the inner food component is aligned vertically. 8. The instrument under either claim 6 or 7, which includes the following: an instrument for controlling the external food-feeding impeller pump, in which the instrument measures the angle of rotation of the external food-feeding impeller pump rotor and controls the external food-feeding impeller pump so that it switches between a base rate of rotation and a rate of rotation higher than this base rate, while the impellers, which are arranged on the rotor concentricity at uniformly equal intervals, move to deliver food to the outlet flow path, and the switching of the rotor rotation rate is repeated in accordance with the position of rotation of each individual impeller. 9. The equipment as provided in either claim 6 or 7, which includes the following: transfer rollers positioned alongside the external impeller pump to transfer material received in the external feed hopper to the external impeller pump by rotating the transfer rollers; and a screw conveyor positioned below the internal feed hopper to transfer material received in the internal feed hopper to the internal impeller pump by rotating the screw conveyor. 10.
