The cooling efficiency of the evaporative cooling chamber was found to be 65.41%, 56.14% and 89.94% for month of September, October and November, respectively. The average yellowness index before and after storage of okra was 33.97 and 44.95, respectively and for snake gourd before and after storage was 40.46 and 32.17, respectively. The hardness of okra before storage was 1060g and after storage was 811.6g. The hardness for snake gourd before storage and after storage was 1626.6g and 838.3g respectively. Shelf life was increased by four days and six days of okra and snake gourd, respectively in evaporative cooling chamber as compared to ambient environment.Keywords

A 200 litre oil drum was developed and fabricated for production of bamboo vinegar. Bamboos were cut in 15 cm length and further splitted vertically. The average moisture content of air dried bamboo splits was found to be 22.77 per cent. The bamboo splits were carbonized in oil drum kiln and smoke was condensed to collect bamboo vinegar. It was observed that from 16 bamboos, the output of bamboo vinegar 2.24 litre and bamboo charcoal 22.3 kg was obtained. The average bulk density of bamboo charcoal was found to be 181.23 kg/m3. The ash content of bamboo charcoal and raw bamboo were found to be 4.28 per cent and 7.88 per cent, respectively.Keywords

Cashew (Anacardium Occidentale L.) is one of the important tropical crops having high export potential due to high market value of kernels. In the study "Vegurla-4" variety of cashewnut was processed by direct steam roasting method for studying maximum per cent whole kernel recovery, drying behaviour of kernels and sensory properties of cashew kernel. The treatments were combinations of steam pressure viz., 10, 15 and 20 psi and time of steaming viz., 10, 15 and 20 min. Statistical R. B. D. analysis revealed that the treatment 20 psi with 10 min. gave maximum 90.08 per cent whole kernels. The pressure factor was significant while time factor was found to be non-significant in 32 factorial designs. The mathematical model developed gave the optimum pressure 18.76 psi for maximum shelling percentage. The treatment consisting of 15 psi and 15 min gave better result during drying study with lowest equilibrium moisture content and highest drying constant. The sensory study revealed that among treatments colour and texture varied significantly. Overall, treatment with steam pressure 20 psi and steaming time 15 min. was found to be most suitable.Keywords

Three varieties of bamboo viz., Dedrocalamus ritchy (Manga), Dendrocalamus stocksii (Mes) and Dendrocalamus strictus (Manvel) were used to prepare bamboo mats were weaved manually and treated with glue. Urea formaldehyde (resin) was used as glue to prepare bamboo mat boards. The resin application was done by dipping. Bamboo mats were dipped for 10 min in urea formaldehyde. 30 kg of resin was required for complete dipping of bamboo mats. Mats were pressed together at 110°C temperatures and pressure of 150 kg/cm2 was applied for 5 min. This is for spreading glue properly. Mats were again pressed at 110°C at a pressure of 200 kg/cm2 for 10 min to from bamboo mat boards. Boards were trimmed to a size of 2.1 m × 1.2 m board of 9 mm, 12 mm and 16 mm thickness were prepared. Bamboo mat board can be prepared from Dendrocalamus stocksii (Mes), Dedrocalamus ritchy (Manga) and Dendrocalamus strictus (Manvel) using urea formaldehyde resin. Dedrocalamus ritchy (Manga) was easy to prepare slivers of bamboo. Density of bamboo mat board increased as thickness increases. Maximum density was for Dendrocalamus stocksii (Mes). Water absorption bamboo mat board decreased as thickness increases and was minimum for Dendrocalamus stocksii (Mes). Tensile strength and compressive strength for bamboo mat board increased as thickness increases. For Dendrocalamus stocksii (Mes) maximum tensile strength and maximum compressive strength was 37.83, 43.21 and 48.50 N/mm2and 15.75, 19.21 and 26.30N/mm2 for 9, 12 and 16 mm thickness, respectively.Keywords
