AI Technical Summary
Technical Problem
Existing straining devices for food ingredients like chestnuts and sweet potatoes face inefficiencies in discharge, leading to increased pressure, heat generation, and flavor deterioration due to friction, especially when producing a paste.
Method used
A straining device with a dual-screw mechanism, where the first screw section transports food ingredients downstream and the second screw section extrudes them through holes, reducing pressure and friction, while maintaining flavor by minimizing heat generation.
Benefits of technology
The device efficiently extrudes food ingredients as a fluffy paste with improved flavor by reducing friction-induced heat and pressure, ensuring effective discharge without stickiness.

Abstract
To provide a sieving machine capable of preventing degradation of the quality of ingredient paste due to excessive pressure when sieving the ingredient paste from steamed food ingredients such as chestnuts or sweet potatoes, while improving the efficiency of collecting high-quality ingredient paste.SOLUTION: A sieving drum having numerous through-holes on its outer peripheral surface for sieving ingredient paste is provided with an internal screw composed of a first screw portion and a second screw portion of different shapes. The upstream side of the sieving drum is closed, and the other end being the downstream side is detachably or openably closed. On the upstream side of the transfer within the sieving drum, the first screw portion, which is helically formed, and the second screw portion, which is helically formed and continuously downstream of the first screw portion, are rotatably provided. The transfer flow rate of the food ingredient in the first screw portion is set to be greater than that in the second screw portion. In addition, the upstream slope of the transfer path in the second screw portion is made gentle so that the food ingredient is pressed outward through the through-holes and converted into the ingredient paste.SELECTED DRAWING: Figure 1
