Background
Sucralose is used as a novel sweet food additive, has more advantages than sucrose, saccharin, AK sugar, aspartame, stevioside and the like, has high safety and stable performance, is a novel high-quality non-nutritional high-efficiency sweetener, and is an optimal ideal sweet substitute for foods for patients with obesity, cardiovascular diseases and diabetes mellitus; also belongs to the field of fine chemical products, and is a branch product of food additives. It has not only rapidly expanded application range in health food and medicine, but also widely applied to more than 300 processed products such as baked food, beverage, chewing coffee, dairy products, frozen dessert, ice cream, pudding, jelly, jam, syrup and the like, and has been widely accepted by the market at present and becomes one of the most popular high-potency sweeteners.
In the esterification working section, syrup concentration is the last working procedure, and the aim is to concentrate the dilute syrup and then send the concentrated syrup to the chlorination working section for treatment; however, the syrup concentration process has many problems, such as too long single-kettle concentration time; the syrup index after concentration has large fluctuation; the system has more materials, the concentration kettle has more times, the workload of workers is large, and the like.
Disclosure of Invention
The invention aims to solve the problems of high energy consumption, long time consumption, complex operation and the like in the single-kettle concentration process of syrup in the existing sucralose production, and provides a method for continuously concentrating sucralose syrup.
In order to achieve the purpose, the technical scheme adopted by the invention is as follows:
a method for continuously concentrating sucralose syrup is characterized by comprising the following steps:
(1) checking whether equipment such as a material pumping pump, a vacuum pump, a DMF single-effect evaporator, a condenser, circulating water and the like are intact;
(2) starting a syrup feeding pump, and pumping syrup in a syrup storage tank into a DMF single-effect evaporator at a flow rate of 3500-4000L/h;
(3) slowly opening a hot water valve of the DMF single-effect evaporator to adjust the temperature, opening a vacuum pump, opening a circulating pump of the DMF single-effect evaporator, opening circulating water and a brine valve of a condenser to carry out evaporation concentration, and controlling the temperature of the DMF single-effect evaporator to be 60-70 ℃ and the vacuum degree to be-0.088 to-0.095 KPa;
(4) condensing a light phase (DMF) from the top of the DMF single-effect evaporator, then feeding the condensed light phase (DMF) into a DMF storage tank (the extraction amount is 2500-3000L/h), and then feeding the condensed light phase (DMF) into a storage area;
(5) and (3) taking out the heavy phase at the bottom of the DMF single-effect evaporator at 1000-1500L/h, sending the heavy phase to a concentration kettle for re-concentration, controlling the temperature of the concentration kettle to be 60-70 ℃ and the vacuum degree to be-0.090 to-0.095 KPa, concentrating for 4-4.5h, sending the concentrated heavy phase to a concentrated syrup storage tank, and then sending the concentrated heavy phase to a chlorination working section.
The invention mainly utilizes different evaporation and concentration efficiencies of different concentration equipment, combines the characteristics of materials, selects proper concentration equipment according to the process characteristics, and is matched for use, thereby improving the concentration efficiency.
Compared with single-kettle concentration, the method has the following advantages:
the syrup is continuously sent to a single-effect heater for concentration, the syrup is concentrated by 80% of the concentration amount in the concentration step in the single effect by measuring the syrup content and controlling the feeding amount and the discharging amount, and then the extracted syrup is sent to a concentration kettle for continuous secondary concentration, the concentration is controlled well to control the moisture content (1.5-2.0%) and the acidity (1.5-2.0), the integral concentration time can be greatly shortened (from 8-8.5h to 4-4.5 h), the sugar liquid loss in the concentration process is reduced, the integral conversion rate of the esterified syrup is improved by 1.3%, and great economic benefit is created.
