Analyses:

Laboratory analyzes:

This laboratory occupies an area of 192 m2, air-conditioned environment and it was put in operating condition at the beginning of 2001. Specificity by routine analytical, it is sectorized into 03 divisions well feature:
· Division of Research;
· Analysis Division;
· Imaging Division and Microbiology.

 

Research division:

It occupies the largest area of the laboratory, as it is configured to meet practical classes and training courses, and facilities of individual work surface allow students, professors, researchers, etc, performing research activities, and also there are support technicians, who assist in the use of higher resolution devices.

The division has more than three rooms, which are leased analytical equipment for advanced chemical analysis such as gas chromatography with mass detector (GC-Mass), gas chromatograph with FID detector (GC), gas chromatograph for infrared (TOC), liquid chromatograph (HPLC), liquid chromatograph for size exclusion (HPSEC), infrared spectrophotometer FT-IR spectrophotometer UV / VIS diode array detector, viscograph RVA, exhaust chapels, refrigerated centrifuge and other equipment of bench.

 

Imaging and Microbiology Division

The imaging division has microscope equipped with video camera attached to a computer that processes images via software making discrimination by optical characteristics, color, density, etc. The demands arising from research directed toward foods rely on microbiological analysis in environment and adequate infrastructure to prevent unwanted contamination.

 

Analysis Division

It performs routine tests meeting the demands of research and projects in cooperation with other researchers and external community such as cooperatives, agro-industries, food industries and other.

 

 

Processes:

This laboratory has a floor area of 300m2, and it is intended to house equipment and systems to process tropical tuberous.

Two Divisions group and organize activities at this Laboratory:

 

Products Division:

It has an infrastructure geared to the production of final food.

It has a system of expanded production by extrusion, with control panel processes, complete dryer kiln, tablet making and accessories. For the production of modified and hydrolysates starches, there is a complete system of reactors with stirring and control, the heat exchanger, gas boiler, steam lines, and purging central utilities with icy water line, distribution of compressed air, vacuum pump with capture system. Other equipment is the system of spray drying, distillation system for continuous flow in packed column in borosilicate, tangential ultrafiltration system for membrane production system of pasta, breads, containing Kneading, sprinkler turbo type furnace, electric furnace and microwave, electric fryers, stainless steel tables, ice making machine, forms, various tools, etc.

 

Development Division:

It contains equipment to support the development of products such as freezer, industrial refrigerator, microwave oven, disintegrating type knife mills, drying ovens for hot air circulation, and support individual workbenches, warehouse, bench equipment maintenance, adjustments / mounting prototypes system separation by vibratory sieving, etc.

 

Processing of Raw Materials:

This laboratory became operational in late 2000, and it supplies of raw plant research proposals in the theme of tropical roots, therefore, it is responsible for the provision of equipment for the study of starches, gums, biomolecules, polysaccharides, fibers, waste processing, etc.

 

Processing Division:

Where extractions of starches are made, waste and by-products that will be analyzed later for characterization. It has a line extraction pilot size that simulates an industrial system where dozens of pounds of roots are washed, crushed, centrifuged, filtered and dried in a vacuum dryer-type flash dryer delivering products and sub-products of the same type to treatment in high scale. The mass balances are evaluated. Another pilot line manufacturing of flour containing gas oven with temperature controlled trials for research and training of human resources. The processed raw materials are originating from grown collections by Cerat, regional surveys of landraces, i.e., varieties of dozens of species can be processed at this Laboratory.

 

Agronomy Division:

Responsible for the areas of plant production featuring greenhouse with misting (40m2) for acclimatization and adaptation of seedlings grown "in vitro" that were transplanted into special substrate. After adjustment they are transferred to another greenhouse culture (100m2) where they receive light and humidity controlled by automatic sprinklers to finally go into the field for extensive cultivation "in vivo". In glasshouses, plants receive phytosanitary tratment against fungi, parasites, etc. The maintenance of species and varieties in the experimental areas need care as fertilization, irrigation, weeding, harvesting, assessments of climate parameters, etc.

The experimental plots occupy an area of 2.000m2 divided into four sub-areas of 500m2 containing a gravity irrigation system and drip-hose type "quen-gil" independents that offer opportunities to meet different water demands of tropical root crops installed.

DISTANCE LEARNING:

Course: Cassava Production

It shows the process of production of flour with cassava production steps, equipment and mass balance of the process.

The courses offered by Cerat seek to contribute to the training of undergraduates, graduate students, technicians and entrepreneurs interested in the theme of tropical roots and tubers. The Center performs as an extension activity and transfer of knowledge and technologies in the research developed by postgraduate students and researchers

The Central Multimedia Course EAD offers explanatory films, photos experiments and lectures of the courses developed by researchers from Cerat.

 

What´s EAD?

The course EAD is an educational process in which learning takes place at a distance, i.e., participant (student) and educator (professor) are physically distant. With the computer-mediated distance learning, participants study site and time that best suits them, and at your own pace, and can more easily combine learning with personal and professional commitments.
