Sugar boiling automatic control device

Abstract

The invention provides a sugar boiling automatic control device and relates to a device for controlling several main parameters of a sugar boiling pot automatically. The sugar boiling automatic control device comprises a vacuum control module, a massecuite brix control module, a heating steam pressure control module and a sugar boiling pot liquid level control module. The vacuum control module measures vacuum of the sugar boiling pot through a transmitter and uses a distributed control system (DCS) for regulating a condenser inlet circulating water regulating valve so as to control the vacuum. The massecuite brix control module measures brix of syrupy through a brix meter and controls a feed valve, a water inlet valve and sugar boiling time through the DCS. The heating steam pressure control module measures steam pressure of the sugar boiling pot through a pressure transmitter and uses a DCS for controlling amount of heating steam entering the sugar boiling pot. The sugar boiling pot liquid level control module measures liquid level of the syrupy of the sugar boiling pot through a liquid level transmitter and controls a feed valve and a water inlet valve of the sugar boiling pot through the DCS. The sugar boiling automatic control device achieves full-automatic sugar boiling, effectively improves reliability and economic benefit of sugar boiling control, greatly reduces consumption of water and steam, reduces faulty operation, lowers accident rate, and improves sugar output.

Description

technical field [0001] The patent of the present invention relates to sugar making technology, especially an automatic control device for the sugar boiling process. Background technique [0002] For a long time, sugar enterprises have only paid attention to the economy of initial investment, and the investment in automation of the production process is very limited. Only equipped with on-site thermometers and pressure gauges, the hammer control of syrup relies more on the experience of the operator, resulting in poor controllability and low reliability. It often occurs under the same operating conditions during the production process. Different quality products are obtained due to human factors, which consumes a lot of water and steam, takes a long time, and is easy to cause misoperation due to different reasons, and the accident rate is high. Contents of the invention [0003] The purpose of the present invention is to aim at the defects existing in the control and manag...
