Here, let's briefly talk about the process of sugarcane sugar production

There are two methods for extracting sugarcane juice from sugarcane: pressing and exudation. The squeezing method is a method of extracting sugarcane juice through pretreatment and the combination of squeezing equipment and infiltration system. The exudation method is a method in which sugarcane is pre treated and crushed, and through the use of exudation equipment and a certain juice flow system, the sugarcane material is infiltrated with water and dilute sugar juice to continuously leach and wash out the sugarcane sugar content.

Sugarcane pressing method

The principle of squeezing and extracting juice is primarily to cut sugarcane into filamentous and sheet-like pieces, which are then fed into a press. This causes the cell walls of sugarcane cells filled with juice to rupture under the pressure of the press rollers and oil pressure. The sugarcane is compressed, and the cells are flattened while the juice is discharged; By using the infiltration system, the expanded bagasse discharged from the press is added with water or diluted with juice to dilute the sugar content inside the cells and extract more sugarcane juice.

Sugarcane is repeatedly pressed through several three roll presses. Add water for infiltration before the sugarcane enters the final press. The participating water is called infiltration water, and the general dosage is 15-25% of the amount of sugarcane. The juice extracted from the last press is called the last press juice, which is then pumped into the previous press as the leachate. The sugarcane material that enters the press is then infiltrated, and the diluted juice is then used as the leachate from the previous press until it reaches the second press. This is the compound infiltration method widely used in sugar factories. The juice squeezed by the * * and second presses is combined into a mixed juice and sent for purification treatment. The sugarcane material discharged from the last press is called bagasse. The moisture content in bagasse is 45-50%, sugar content is 1-4%, fiber content is 45-52%, and soluble solids are 1.5-6%. Bagasse is sent to boilers as fuel or used as other industrial raw materials. The sugar extraction rate is used to measure the sugar extraction power of the juice extraction method, which is defined as the mass percentage of sucrose extracted from sugarcane to the sucrose in sugarcane. The sugar extraction rate of sugarcane mills is between 92% and 97%.

The primary equipment for squeezing and extracting juice includes a sugarcane cutter, a press and its driving equipment, an infiltration system, and corresponding conveying equipment. The sugarcane cutter consists of a cane cutter and driving equipment. The press machine consists of three rollers and a frame. The rollers of the three roll press are embedded into triangles and are called the top roller, front roller, and rear roller according to their respective orientations. There is a certain gap between the top roller and the front and rear rollers. The shaft ends of the three rollers are equipped with transmission teeth, and the top rollers are driven by a prime mover such as an electric motor, steam turbine, or steam engine through a deceleration device, and then the three squeezing rollers roll at the same speed.

The production capacity of sugarcane factories is indicated by the daily crushing of sugarcane tons by the factories. The ability to handle sugarcane is related to factors such as the number of crushing machines, sugarcane crushing degree, diameter and length of the crushing rollers, roller speed, sugarcane fiber content, and requirements for sugar extraction. Generally, sugar mills use 4-6 presses to form a row of presses. Two or three columns are also selected to meet production needs.

The chemical composition of sugarcane juice varies with the chemical composition of sugarcane, the storage time after harvesting, and the environment. Table 1 [Cane Juice Composition] shows the chemical composition of sugarcane juice.

Since the late 1980s, sugarcane juice extraction skills have tended to strengthen sugarcane pretreatment, increasing the crushing degree to 70-80%; Pay attention to the selection of high-level feeding slots, perhaps using pressure feeding rollers (also known as toothed feeding rollers) to form a five roll press with a traditional three roll press, in order to strengthen the feeding of the press, perform pre compression, and then improve the production capacity of the press; On the other hand, in the infiltration process, on the basis of the compound infiltration system, a large part of the dilute juice from the press is selected to reflux to the main press, so as to increase the infiltration amount without increasing the infiltration water amount, so that the liquid content of bagasse reaches saturation and presents a full infiltration, fully infiltrating and diluting the residual sugar content of the sugarcane material, and achieving the intention of further improving sugar extraction.

The squeezing method consumes a lot of steel and electricity, but it has the advantages of strong adaptability in sugarcane processing, convenient skill management, and reliable operation, making it still the primary method for sugarcane juice extraction.

Sugarcane exudation method

The basic principle of sugarcane exudation method is to use a layer of cytoplasmic membrane between the cytoplasm and cell wall in sugarcane cells, which can selectively absorb substances outside the cells. Therefore, the leaching operation of solid-liquid extraction can be applied to transport sucrose molecules from sugarcane into the exudate juice through washing, dilution, permeation, and diffusion effects, achieving the intention of extracting sugar. The sugarcane juice extraction process mainly includes sugarcane pretreatment, sugar exudation, and wet bagasse dehydration. The exudation process can be further divided into two categories: one is the exudation of sugarcane shreds, which are pre treated into sugarcane shreds and then enter the exudator, where the exudate juice is obtained by soaking the exudate water and dilute juice; One type is bagasse exudation, in which the pre treated sugarcane shreds are first processed by a press machine to extract 60-80% of the original sugarcane juice, which is equivalent to the sugar content of sugarcane. Then, they enter the exudator for further exudation and juice extraction. The squeezed original sugarcane juice and the exudate juice are combined to form a mixed juice and sent for purification treatment. The sugarcane material that comes out of the diffuser is called wet bagasse, with a moisture content of about 85%. It is dehydrated by the dehydration equipment, reducing the moisture content to below 50%, and then sent to the boiler as fuel or other industrial raw materials. The dilute juice obtained from the dehydration equipment is called dehydrated juice, which is generally purified by chemical and physical methods such as phosphoric acid, lime, and heating. The clear juice is then directed back to the diffuser to assist in extraction and recovery of sugar. The sugar extraction rate of the exudation method is generally the same as that of the pressing method.

The sugarcane pretreatment process requires a crushing degree of 75-80% for bagasse exudation method and 85-90% for sugarcane silk exudation method. The sugarcane silk is fine and flaky, and there should not be too much sugarcane chips to facilitate more effective infiltration of sugarcane sugar. Preprocessing equipment commonly uses tearing machines or heavy hammer tearing machines, sugarcane cutters, or their combination equipment. Dehydration equipment often uses a three roll press. There are various forms of diffusers, including Silver type, BMA type, De Smet type, DdS type, and Saturn type. Different forms of diffusers have their own characteristics, but the process effect is roughly the same. Various diffusers have moving components and graded leaching systems that continuously move or rotate the sugarcane material forward. The preprocessed sugarcane is fed into one end of the diffuser, and at the other end, about 25% of the sugarcane content is added to the leachate to extract sugar, and wet sugarcane bagasse is discharged from this end. With the help of a multi-stage infiltration system, the sugarcane and extract are fully immersed in multi-stage countercurrent filtration, and the exuded juice is discharged from the end of the sugarcane feed. The infiltration system is divided into 12 to 18 stages, with a infiltration time of 20 to 35 minutes; Bagasse exudation takes 8-12 levels, and the exudation time is 16-26 minutes. The exudation temperature is achieved by heating and leaching the juice to maintain a temperature of 80-90 ℃ in the hot cracking zone of the exudator, and a final exudation temperature of 50-65 ℃. The primary factors affecting the extraction power of exuded sugar are sugarcane fragmentation, exudation temperature, timing, and the amount of water involved in the exudation. The production capability of the diffuser primarily depends on its standard size and the flow rate of juice through the sugarcane layer. The factors that affect the speed of sugarcane juice flowing through the sugarcane layer are sugarcane quality, pre-treatment fragmentation, sugarcane layer thickness, dehydrated juice quality, and exudation temperature.

The exudation extraction method has advantages such as saving steel, power, investment, and repair costs. But skill management requires high requirements and consumes a lot of steam. By relying on the chemical and physicochemical effects of detergents and heating, and through solid-liquid separation methods, various non sugar substances that affect sucrose crystallization in the mixed juice are removed as much as possible to obtain a clear and pure juice with lower color value.
