Description

Technical Field

[0001] This utility model relates to the field of sterilization autoclave technology, and in particular to a fully automatic spray sterilization autoclave. Background Technology

[0002] A sterilizing autoclave, also known as a sterilizing pot or sterilization machine, is mainly used in the food industry, pharmaceutical industry, and other fields. The autoclave consists of a pot body, lid, opening device, locking wedge, safety interlock device, track, sterilization basket, steam spray pipe, and several inlets. The lid is sealed with an inflatable silicone rubber heat-resistant sealing ring, ensuring reliable sealing and a long service life. Using pressurized steam as a heat source, it features a large heating area, high thermal efficiency, uniform heating, short boiling time for liquids, and easy temperature control. The inner pot body is made of acid- and heat-resistant austenitic stainless steel and is equipped with a pressure gauge and safety valve. It is aesthetically pleasing, easy to install, convenient to operate, and safe and reliable.

[0003] In food processing and pharmaceutical production, sterilization is a crucial step in ensuring product quality and safety. Traditional steam sterilization and hot water sterilization processes often result in uneven temperature distribution within the autoclave, which can lead to incomplete sterilization or overheating of some products, affecting product quality. To address these issues, we propose a fully automatic spray-type sterilization autoclave. Utility Model Content
