Every year around 173 million tonnes of sugar are consumed worldwide, an average of 24 kilograms per capita. As well as being one of the most important commodities in the global food industry, sugar is playing an increasing role as a green alternative to fossil fuel.
Sugar is produced in approximately 120 countries from sugar cane and sugar beet. Cane sugar makes up 80 % of total annual production and is the primary source for 70 countries, while 40 countries rely on beet crops. Only ten countries produce sugar from both sources. The top ten sugar producers, headed by Brazil, India and the EU, account for 75% of global supply.
Despite price fluctuations in recent years and increasing competition among processing companies, sugar is forecast to continue its upward trend. World production is expected to grow by 2.1% per year to reach 210 million tonnes by 2025.
The growing awareness of the effects of greenhouse gases has prompted governments to support the production of biofuels, including ethanol from sugar, as an environmentally-friendly replacement for gasoline. As a result, the ethanol market has grown rapidly, particularly in Brazil, the US and the EU. Biofuel consumption is also on the rise in the Asia-Pacific region.
Meeting the growing demand for sugar means higher production costs and use of energy. At Grano, we provide innovative engineering solutions for all applications in the sugar industry. Our state-of-the-art range of heat exchange technology and expertise enables customers to operate profitably and energy efficiently.
China is one of the earliest countries in the world to produce sugar through the cane. At present, according to the different sugar technology, can be divided into vulcanized sugar and carbonized sugar. At present, the majority of domestic sugar production is vulcanized sugar. Cane sugar manufacture mainly includes extraction of the juice, clean, evaporation, crystallization, sub-honey and dry. The plate heat exchanger is mainly used for the preheating of the cleaning process and the preheating of the thick syrup in the evaporation process. Heating clear water is always with some impurities, easy to cause a blockage. But Grano's wide-flow plate heat exchanger can solve the problem of clogging and carry out periodic cleaning to achieve a good heating effect.
Cane sugar manufacture mainly includes extraction of the juice, clean, evaporation, crystallization, sub-honey and dry. The clean process of using sulphite and phosphorus float process is shown. The sucrose crude is required to be heated before it is used in the sulphur smoked neutralizer and the settler so that the coarse juice can achieve the most appropriate and the settlement temperature. Grano can provide wide flow plate heat exchanger, with high heat transfer efficiency and accurate temperature control. Then the sucrose coarse juice of the sulphur - smoked neutralizer can be accurately controlled at 55℃~65℃, and the neutralization juice temperature of the settler is controlled at 100℃~103℃, which can make the clean efficiency to the highest.
Sugarcane carbonate process principle is mainly using large amounts of calcium carbonate particles in one carbon filling process which has good adsorption on colloid, pigment and other non-sugar elements to reduce the colour value and improve the purity of the juice, at the same time through the second carbonation to make further adsorption and precipitation impurities. The plate heat exchanger is mainly used for heating the mixture of one carbonation and second carbonation filling process and the heating of the bleaching liquid, so as to reach the optimum reaction temperature and obtain the best clean effect Grano company has operated heat exchangers for many years, can provide you with a full range of sugar heat transfer solutions.
Cane sugar phosphorus float evaporation process is carried out to evaporate the sucrose clear juice from the clean process through the five-effect evaporation system to obtain crude syrup and then further added with phosphoric acid and glycated calcium. The filtrate is separated and filtered by a buoyancy apparatus to obtain clear syrup and then go to the next step. In order to make the evaporation effect significant, it needs to use the plate heat exchanger preheated to a certain temperature before the evaporation process. Sucrose juice contains a variety of impurities, easy to plug the pipeline; wide flow plate heat exchanger is the choice for sugar industry heat transfer. Grano has been selling heat exchangers for many years and will use professional technical knowledge to solve your various sugar problems.
