AI Technical Summary

Technical Problem

Traditional bamboo tube rice dumpling production suffers from poor consistency, low yield, complex operation, unstable sealing, and serious water waste, making it difficult to achieve large-scale and standardized production.

Method used

The bamboo-joint-free zongzi forming demolding device includes a bamboo tube, a lid, a bamboo and wood piston, cotton and hemp rope, a bamboo and wood top rod, and a stainless steel retaining spring. Through the design of the bamboo and wood top rod with a gradually changing diameter and the small-diameter piston at the bottom, combined with the fixing structure of the cotton and hemp rope and the stainless steel retaining spring, efficient demolding and sealing are achieved.

Benefits of technology

It improves the consistency of taste and yield of zongzi, simplifies the operation process, reduces production costs and water waste, supports automated production, and is suitable for modern fast-paced life.

Abstract

The utility model relates to the field of food processing equipment, in particular to a bamboo-joint-free type rice dumpling forming stripper which comprises a bamboo tube, a sealing cover, a bamboo piston, a cotton and hemp rope, a bamboo ejector rod and a stainless steel clamp spring. The sealing cover is detachably fixed to the top of the bamboo tube, and the bamboo piston is embedded into the bottom of the bamboo tube. The cotton and hemp rope is bound outside the bamboo tube, the sealing cover and the bamboo piston; one end of the bamboo top rod penetrates through the bamboo piston and is inserted into the bamboo tube; and the stainless steel clamp spring is embedded into the bottom of the bamboo piston. By adopting the bamboo top rod with the gradually-changed diameter and the built-in bamboo piston structure, the bamboo tube space utilization rate and the demolding efficiency are improved, and rice dumplings are uniformly heated, have consistent taste and are convenient to eat; meanwhile, recyclable materials are used, the sealing and bundling structure is optimized, the sealing performance and stability are enhanced, centralized cleaning and disinfection are facilitated, the production cost is reduced, environmental protection and automatic production are facilitated, the yield and the production efficiency are improved, and a guarantee is provided for large-scale popularization.
