Embodiment 1

[0027] Embodiment 1: a kind of purple waxy corn blanching and cooling process comprises the following steps:

[0028] The high-temperature and high-pressure sterilization process of purple black waxy corn includes a high-pressure boiler A and a high-pressure boiler B, which are connected by connecting pipes, and there are circulation valves on the connecting pipes; the operation steps are as follows:

[0029] The first step: close the hatch of the high-pressure boiler A, pressurize the pot to 2 kg, add 1.3 cubic meters of cold water, and heat the water temperature to 115°C with steam; the second step: use high-temperature-resistant, non-toxic special plastic The vacuum-packed corn is put into a stainless steel cart, which is full of transparent holes, so that water can flow from all angles, and the cart is pushed into the high-pressure boiler B. After the hatch is closed, the pressure in the boiler is increased to 2 kg, open the circulation valve of the connecting pipe between...

Embodiment 2

[0030] Embodiment 2: a kind of purple waxy corn blanching and cooling process comprises the following steps:

[0031] The high-temperature and high-pressure sterilization process of purple black waxy corn includes a high-pressure boiler A and a high-pressure boiler B, which are connected by connecting pipes, and there are circulation valves on the connecting pipes; the operation steps are as follows:

[0032] Step 1: Close the hatch of the high-pressure boiler A, pressurize the pot to 2.5 kg, add 1.7 cubic meters of cold water, and heat the water to 125°C with steam; Step 2: Use high-temperature-resistant, non-toxic special plastic The vacuum-packed corn is put into a stainless steel cart, which is full of transparent holes, so that water can flow from all angles, and the cart is pushed into the high-pressure boiler B. After the hatch is closed, the pressure in the boiler is increased to 2.5 kg, open the connecting pipe circulation valve between high-pressure boiler A and high...

Embodiment 3

[0033] Embodiment 3: a kind of purple waxy corn blanching and cooling process comprises the following steps:

[0034] The high-temperature and high-pressure sterilization process of purple black waxy corn includes a high-pressure boiler A and a high-pressure boiler B, which are connected by connecting pipes, and there are circulation valves on the connecting pipes; the operation steps are as follows:

[0035] Step 1: Close the hatch of the high-pressure boiler A, pressurize the pot to 2.2 kg, add 1.5 cubic meters of cold water, and heat the water to 120°C with steam; Step 2: Use high-temperature-resistant, non-toxic special plastic The vacuum-packed corn is put into a stainless steel cart, which is full of transparent holes, so that water can flow from all angles. The cart is pushed into the high-pressure boiler B, and the pressure in the boiler is increased to 2.2 kg, open the connecting pipe circulation valve between high-pressure boiler A and high-pressure boiler B to let t...

Abstract

The invention discloses a high temperature and high pressure sterilization process for purplish black waxy corn and relates to the field of food processing. The sterilization process comprises the steps of placing the corn which is packed ready into a stainless steel push cart, pushing the push cart into a high pressure boiler B, closing a cabin door, raising the pressure inside the boiler to 1.8-2.2 Mpa kilograms, opening a connecting pipe circulation valve between a high pressure boiler A and the high pressure boiler B so that water in the high pressure boiler A can flow into the high pressure boiler B in a circulating mode, and utilizing water pump power to push the water in the high pressure boiler B to circulate and conduct sterilization. By means of the sterilization process, product consumption and economic loss can be reduced, the storage time of the vacuum package corn is prolonged, the quality of the vacuum package corn is improved, and economic income is increased.

Description

technical field [0001] The invention relates to the field of food processing. Background technique [0002] If vacuum-packed corn is not sterilized by high temperature, insects, deterioration, and packaging bag expansion will occur after a long time, seriously affecting food safety and causing large economic losses to the company.
