An efficient sterilization process for fruit cans

Abstract

An efficient sterilization process for fruit cans is disclosed. The process includes subjecting sealed fruit cans to low-temperature microwave sterilization in a microwave tunnel; then inverting and rotating the cans for 5-10 rows, performing low-temperature sterilization in a sterilization tank and rapidly cooling the fruit cans. Beneficial effects of the process are that the sterilization temperature is low, the fruit cans can be inverted so that heat conduction in the cans is accelerated and sterilization effects are uniform, loss of nutrition of fruits is low, and a higher sterilization efficiency is ensured.

Description

technical field [0001] The invention relates to food processing technology, in particular to a high-efficiency sterilization method for canned fruit. Background technique [0002] Sterilization treatment is usually required before canning, and most of the existing sterilization processes are boiling sterilization or microwave sterilization. Boiling sterilization is to immerse the sealed cans in water and then boil them at high temperature. Due to the high temperature, the vitamin C and other nutrients in the fruit will be destroyed. However, microwave sterilization mostly adopts intermittent and continuous methods. The former can be rotated by a turntable. The latter can only go forward; the sterilization effect cannot be achieved; at the same time, the existing traditional fruit sterilization process is generally suitable for small-package cans, even if the fruit near the filling wall is scalded, the central part of the filling has not received sterilization treatment.
