Parameters of Quality in the Production of Piloncillo in Sabanas Huatusco, Veracruz

The development of panela or brown sugar in Mexico takes place in small factories or mills commonly called rural agribusinesses. The process is usually handmade, it does not have quality control measures such as good manufacturing practices (GMP) and measurement of physicochemical parameters that can be monitored by the producers to ensure the quality and safety of the product. The importance to evaluate these parameters to contribute to a continuous improvement process to obtain a competitive product in the market. The aim of this study was to determine the quality parameters in each stage of preparation of brown sugar and the final product, by characterizing, monitoring, control and physicochemical analysis of different samples obtained during the process. The results obtained on physicochemical parameters such as humidity, PH, Color Icumsa, ° Brix, Pol, Purity, in the stages of milling or cane juice extraction, concentration of juice or cane syrup and final product, show that they are affected by the degree of maturity and variety of cane used, and the time exposed to high temperature, meladura (cane honey) concentration and adequate filtration process and clarification.

Improved fuzzy logic controller for cane juice extraction

In current days Fuzzy logic plays auspicious role to provide so many choices for many applications which are system control. Fuzzy logic having no. of practical methodologies in soft computing. Sugar making industries are one of the applications using fuzzy logic controller. sugarcane juice extraction is an industry which is highly seasonable. If the supply of sugar cane is irregular then that reduces the efficiency of extractor from cane to mass producing sugar. So, it is necessary to improve the efficiency of extractor, which gives juice from cane billets. For that we must keep up the Donnelly height (or) level of cane is closed to 90cm. Where a methodology introduced to improve the three inputs controller with fuzzy is used to keep up the cane volume (or) level of Donnelly channel. For that cane level must and should always at 90cm. To limited that level (or) height of cane in chute (or) channel was developed by using of tool box in fuzzy logic designer, MATLAB software.

FPGA Implementation of Variable Feed Rate Algorithm for a Three Input Fuzzy Controller to Maintain the Cane Level

Fuzzy logic which is one of methodology of soft computing has provided to be brilliant choice for the many control system application. Fuzzy logic is practical to numerous fields. One of the uses of fuzzy logic is in sugar mill. It is very important to produce sugar at low cost. Irregular supply of sugar cane decreases the efficiency of cane juice extraction during manufacturing of sugar. To increase the efficiency of cane juice extraction it is necessary to sustain the cane height at desired level inside Donnelly chute. A methodology to develop a variable feed rate algorithm for three inputs fuzzy controller sustains the cane height at desired level and was developed with fuzzy logic tool box of MATLAB software. The developed fuzzy controller can be implemented by using HDL language and Xilinx Vivado 2016.2.

Selection of Xilose-Fermenting Yeast Strains

In Brazil, ethanol is obtained by fermentat of sugar cane juice using Saccharomyces cerevisiae. The cane juice extraction generates the bagasse that has been used for obtaining generation biofuel. However, the sugarcane bagasse has 30% pentose that cannot be fermented to ethanol by S. cerevisiae. Thus the aim of this study was to isolate a yeast able to ferment xylose to ethanol. Samples of cane juice and flowers were used for the isolation of 165 strains that were then screened for ethanol production using plate testing. Among them, the ethanol positive strains Wickerhamomyces anomalus, Schizosaccharomyces pombe and Starmerella meliponinorum were selected for a xylose fermentation assay, using a semi-synthetic and bagasse hydrolysate as must. S. meliponinorum and S. pombe produced 0.63 and 2.7 gL-1 of ethanol, respectively, from xylose in a semisynthetic medium. In the medium consisting of bagasse hydrolysate must, 0.67 and 1.1 gL-1 of ethanol were obtained from S. meliponinorum and S. pombe, respectively. All the yeasts produced xylitol from xylose in the semisynthetic medium and S. meliponinorum was that which produced the highest quantity (14.5 g L-1).

Design Algorithm and Performance Analysis of Conventional and Fuzzy Controller for Maintaining the Cane Level during Sugar Making Process

The amount of cane fiber carried by cane carrier varies due to non-uniformity of cane supply. The continuous variation of cane in chute during the cane juice extraction inversely affects the cane juice extraction efficiency of mill. This paper deals with the development and performance comparison of conventional controller and fuzzy controller to maintain the cane level in chute during juice extraction. The conventional controller is developed using VHDL language and simulated by using Xilinx ISE 14.5 version. The fuzzy controller is developed and simulated by using fuzzy toolbox of MATLAB ® version 7.11.0.584 (R2020b).

Statistical optimization of alkaline hydrogen peroxide pretreatment of sugarcane bagasse for enzymatic saccharification with Tween 80 using response surface methodology

Sugarcane bagasse is a byproduct constituting more than 25 % processed matter after cane juice extraction and is thus a low-cost renewable substrate for value-added products such as bioethanol and xylitol due to its high content of hemicellulose and cellulose. In this study, a Box–Behnken response surface method design was used to optimize alkaline hydrogen peroxide pretreatment of dilute acid-treated sugarcane bagasse. Hydrogen peroxide concentration (2–6 % w/v), pretreatment time (10–40 h) and liquid/solid ratio (8–20 v/w) were tested in order to maximize glucose production in the enzymatic hydrolysis process. The optimum conditions obtained were 4.7 % w/v hydrogen peroxide concentration, 26.7-h pretreatment time, and 17.1 v/w liquid/solid ratio, producing 31.1 g/L glucose (40.2 % glucose yield) at 72-h hydrolysis. After optimizing alkaline hydrogen peroxide pretreatment, a second Box–Behnken design was used to evaluate the effects of cellulase loading (3.4–5.6 filter paper unit (FPU)/g solid), β-glucosidase loading (15–27 beta-glucosidase unit (CBU)/g solid) and Tween 80 concentration (0.11–1.7 % w/v) on glucose production during enzymatic hydrolysis. By analyzing response surface plots and time course hydrolysis, 50.1 g/L glucose (64.8 % glucose yield) was obtained at 120-h hydrolysis using 4.1 FPU/g solids for cellulase, 18.2 CBU/g solids for β-glucosidase and 0.95 % w/v for Tween 80. This yield corresponds to a 29 % improvement in glucose concentration compared to no Tween 80 addition.

Ethanol Production from Sugar Cane: Assessing the Possibilities of Improving Energy Efficiency through Exergetic Cost Analysis

The sugar and ethanol production is one of the most important economical activities in Brazil, mainly due its high efficiency and competitiveness. Ethanol production is done by a series of steps: juice extraction, treatment, fermentation, and distillation. The juice extraction and treatment is a common operation of both the sugar and ethanol industries. The process begins with the sugar cane juice extraction, usually done by mills, where the cane is compressed between large cylinders for the separation of the juice from the bagasse. Recently, a juice extraction system, called a diffuser, was introduced in some sugar and ethanol plants. In diffusers, after the sugar cane preparation stage was completed with knives and shredders, the cane passes through a bed where the juice is separated from bagasse by the addition of imbibition water and steam, resulting in a leaching process. The present study evaluates different possibilities of decreasing the thermal energy consumption through exergetic cost analysis. The base case is a traditional ethanol production plant, for which the unitary exergetic cost of ethanol and electrical energy are determined. In the following cases, two proposals were assessed: the use of the diffuser as an extraction system and the use of pinch technology to perform an energetic integration between distillation and extraction (diffuser) systems. The results of exergetic efficiency, irreversibility generation, and unitary exergetic cost of products of the three cases are analyzed and compared. The results show the feasibility of using diffusers and heat recovery to decrease thermal energy consumption in ethanol production plants.
