Embodiment

[0022] In the rice wine sterilizing device before bottling based on high-voltage pulsed electric field technology involved in the present invention, the distance between the high-voltage electrode and the ground electrode is 1 cm. When the peak voltage is 30 kV, the pulse width is 3 μs, and the frequency is The 120 Hz pulse forms a relatively uniform electric field in the effective treatment area, with an average electric field strength of 27.03 kV / cm and a maximum electric field strength of 36.92 kV / cm. Taking Shaoxing rice wine as an example, when its initial temperature is 30 oC, its electrical conductivity is generally 0.2 S / m. Under a pulsed electric field of 27 kV / cm, the effective treatment time is more than 200 μs, and the sterilization number of Saccharomyces cerevisiae in rice wine is above 5 logarithmic levels, that is, 99.999% of Saccharomyces cerevisiae is killed by the pulsed electric field, and the sterilization process The temperature rise of medium-sized rice ...

Abstract

The invention discloses an instant sterilizing device for rice wine before bottling based on high-voltage pulse electric field technology. The stainless steel columns obtained by rotating the four sections with convex middle parts and symmetrical rectangular steps at both ends for a quarter of a circle are respectively used as high-voltage electrodes, ground electrodes and two insulating columnar bodies to form a columnar body structure. The middle double concave The hole is the effective treatment area, and the cylindrical structure insulating rings are respectively installed on the upper and lower rectangular steps of the columnar structure, and an annular cavity for cooling water circulation is formed between the two insulating rings and the columnar structure. The central holes of the upper and lower insulating rings are respectively equipped with the discharge pipe and the feed pipe, and the cooling water inlet pipe and outlet pipe, high voltage electrode and grounding electrode are respectively installed on the upper and lower sides of the first insulating columnar body and the second insulating cylindrical body. Connect with the high voltage pulse generator respectively. The invention can realize the instantaneous low-temperature sterilization of the rice wine before bottling by the high-voltage pulse electric field, and can also improve the quality of the rice wine during the sterilization.

Description

technical field [0001] The invention relates to a sterilizing device, in particular to an instantaneous sterilizing device for rice wine before bottling based on high-voltage pulse electric field technology. Background technique [0002] China's rice wine is one of the three ancient wines in the world. It originated in the land of Wuyue in ancient times (now Jiangsu, Zhejiang and Shanghai), and has a history of more than 2,500 years. Benefiting from the sustained economic growth in recent years, the brewing industry has also reflected structural changes brought about by consumption upgrades: the demand for wine has shifted from "pure hobby" to "nutrition and health care", and the concept of high and strong bad drinking is increasingly being abandoned by people , the advantages of rice wine's low alcohol, nutrition, and health care gradually emerged. Compared with other wines, rice wine is more in line with the general trend of green, nutrition and health in modern society. ...
