Description

“AN IMPROVED SYSTEM FOR SUGAR MANUFACTURING AND

PROCESS THEREOF”

FIELD OF THE INVENTION

The present invention relates to a field of the sugar manufacturing industry. More particularly, the present invention relates to an improved system for sugar manufacturing and the process thereof that enhances the quality of sugar.

BACKGROUND OF THE INVENTION

Sugar is commonly used to refer a crystalline sucrose, a disaccharide compound used throughout the world in food-processing applications as a sweetener. Sugar is primarily produced from the sugarcane plant, a plant that is cultivated in the tropical and semitropical regions of the earth. Throughout the world, manufacturing of sugar from sugarcane is accomplished in two steps:

(a) the raw sugar process; and

(b) the refinery process.

In the raw sugar process, sugar mills convert the harvested sugarcane plant into raw sugar. The raw sugar is transported to sugar refineries, where it is converted into its various refined end products.

In the sugarcane manufacturing industries, the process of manufacturing sugar includes crushing and milling of sugarcane to obtain raw sugarcane juice, clarification and discoloration of raw sugarcane juice to reduce impurities and pigments, five-stage evaporation process to obtain syrup, crystallization of the syrup to obtain crystal sugar, centrifugation, and drying. Further, the clarification and discoloration processes are vital steps to remove impurities from raw sugar juice, which determines the quality of sugar. The clarification and decolonization techniques normally employ carbonization and sulphation methods, which are carried out by the addition of various chemicals such as lime, sulfur dioxide, phosphoric acid, and flocculant. Although these invented methods have been applied in sugar production over the last 100 years, they still have several disadvantages such as failure to provide chemical-free and artificial color-free sugar along with more power consumption and less efficiency.

PRIOR ARTS AND THEIR DISADVANTAGES

The patent application number WO201428948A1 discloses a method of clarifying cane juice, said method including precipitation and filtration of mud solids directly in a sugarcane diffuser thereby avoiding the need for a settling clarifier, said method including the manipulation of a cane bed of the sugarcane diffuser wherein said sugarcane diffuser has a co-current portion, the method including the addition of precipitating agents to the juice in the diffuser. The invention extends to a process for modifying a conventional sugarcane diffuser to improve the quality of juice obtained from the diffuser by reconfiguring the diffuser to include a co-current section and adding manipulation means for manipulating the cane bed.

The drawbacks of the above-mentioned prior art are that it removes suspended solids and colors by using harsh chemicals like lime, sulphatization process and chlorine process resulting in chemically processed sugar. Another disadvantage of the above-mentioned prior art is that the inversion process increases which implies direct decrease in the yield. Further, due to the lengthening of the process and using more energy, the yield of the quality sugar decreases to good quality up to 70%, low grade up to 10% and Z grade up to 20%.

Another document W02008034180 discloses an extract derived from sugar cane having GI (glycemic index) or burn rate-reducing characteristics wherein the extract comprises a mixture of one or more polyphenols, one or more carbohydrates, one or more minerals, and one or more organic acids.

The drawback of the above-mentioned prior art is that the process is complex and costly. Also, the process is for changing the sugar crystallization process. There is more power consumption in the above- mentioned processes.

• Many of the prior art fail to provide a system for sugar manufacturing that reduces the generation of large quantities of waste materials.

• Many of the prior art fail to provide a system for sugar manufacturing that saves energy, volume reduction, decreases the inversion process and saves fresh water.

• Many of the prior art fail to provide a system for sugar manufacturing that eliminates the process of clarification and vacuum filtration. • Many of the prior art fail to provide a system for sugar manufacturing that removes the chemical process for removal of suspended solids, colloidal solids and dissolved impurities.

• Many of the prior art fail to provide a system for sugar manufacturing that reduces the concentration of sugar cane juice.

• Many of the prior art fail to provide a system for sugar manufacturing, the juice received from the filtration have no suspended solids and colloidal matter.

• Many of the prior art fail to provide a system for sugar manufacturing with less power consumption and is thereby, environment friendly.

• Many of the prior art fail to provide a system for sugar manufacturing that is easy to transport and user-friendly.

• Many of the prior art fail to provide a membrane in sugar manufacturing that is not choked.

• Many of the prior art fail to provide a system for sugar manufacturing that uses thermal power saver evaporator.

Filtering the sugarcane juice: After correcting the pH, the raw sugar cane juice is further passed through many filters. Firstly, said juice is passed from the micron bag filter (3) and then from the micron cartridge filter (4).

Removing suspended solids: After the filtration, the juice is passed from said Zeolite chamber (5), wherein the molecules of raw sugarcane juice is break down into 1 /20^th size of suspended solids and dissolved impurities from Sugar cane juice. After removal of said impurities, the juice is passed to the Zeo membrane 1 (6).

Collecting the sugarcane juice: This Zeo membrane 1 (6) removes suspended solids, dissolved impurities, colloidal and microbial particles from sugar cane juice and collects it in the Sugar cane juice tank 1 (8). The sugar cane juice tank 1 (8) collects the filtered sugar cane juice and it is forwarded to the Zeo membrane 2 (9).

Removing dissolved impurities: From the Sugar cane juice tank 1 (8), the juice passes through the Zeo membrane 2 (9). Said Zeo membrane 2 (9) removes pigment, high molecular weight like proteins, fats, wax's, etc., and the filtered sugarcane juice is stored in the said sugarcane juice tank 2 (10), which further carries the juice in the said Zeo membrane 3 (11). Said Zeo membrane 3 (11) removes impurities above 300 Daltons. Evaporating the sugarcane juice to make a syrup: After removing the dissolved impurities, the juice moves to the Evaporator (13) and Condenser (14). Evaporator (13) concentrates the clarified sugarcane juice up to 58% and evaporates the water. The evaporated water is then converted back into liquid state by said Condenser (14).

Crystallizing the sugarcane: The concentrated juice obtained here looks like syrup which is carried further through the processes like clarification for crystallization (16).
