FILTER AND NET PART 2 Dearfriends,
This is 2ndpart of my posting about filter. Here I cover filters which may be moreinteresting. Sincerely, GopalaKrishnan 29-11-2021 8. Vatti, kotta and Muram These areall made using splitting bamboo /cane as thin lengthy pieces and braided to theform different items. The thickness varies between items. Cane made items are costlier. The vatti(small size basket) to handle light weight items has lesser thickness. Muram (winnowingsieve) has thicker strips braided in different forms depending on the states. Kutta (large size basket) is made usingthicker strips and used for carrying things in addition to sieving purpose. Cowdung is applied to winnower. Earlier vattiwas used as a filter for cleaning cut vegetables. Cut vegetables were put in toit and water is added and moved using hand. Washed water was drainedimmediately through the gaps in braiding. In the cooked rice vessel fordraining starch water, vatti was kept in middle and starch water enteringthrough braiding was taken out from it. Now metallic and plastic made sievesare used. Kotta (Basket)is used as a filter by workers while collecting sand from river water. Thediving man will take the sand with water and come up .The water might drainthrough the braiding and wet sand is loaded in country boats. Duringfeasts light weight kotta is used to keep fried papads after placing tissuepaper at bottom. The oil will be absorbed to the paper. In present dayfeasts many items are served in the plantain leaf, before guests enter foreating meals. Two of the items are plantain and papad. Winnower isused as a filter in two ways. One is by blowing it over paddy and wheat. Thepathir (not fertilised light weight paddy) might blow off. During yester years duringmanual rice preparation, winnower was used for removing husk and bran from rice. Slightly hammered paddy was placed onthe winnower and it is moved with both hands up and down with speed. Thecoverings husk and bran might fly off during the moving. Sasthrikalrequire a winnower to keep things handy during all functions. For srardha, thevegetables are arranged and kept in a winnower, the previous day. Winnowerfinds a place in kitchen also on the srardha day. Winnower is used forauspicious, semi auspicious and inauspicious functions among Brahmins. During srardha day waste of vegetables arenot thrown out till srardha is over. It is believed the pithrus coming mayconsume them. Mostly it was kept in a corner of home in the winnower. 9. The EEreasha thorthu Thedouble weaved semi tight towel with small square holes is the favourite item ofall cooks. The coconut milk is obtained after placing the ground coconut meat inthe towel and squeezing. Milk will fall through the tiny holes in the weaving.Nothing can replace the towel for squeezing and getting coconut milk. 10 Metal sieve- arippa It is oneof the kitchen items. Though the side is metallic round the bottom is tiny netusing fibres. Different types of bottom are provided, with ease of replacementas required. Normally I see my wife filter the wheat flour, rava etc. usingthis sieve. For preparing the appam, the rice flour is filtered using arippa. When Iask for ginger use for my stomach uneasiness mini sieve (vati ketti) is used bymy wife to filter ginger juice from ground ginger slightly smashing it. The tea filter is slightly loose fibre or nylonweaved and fitted to metallic framework. 11. Decoction percolator. I have notconsumed decoction coffee in my boy hood days. On those days in boiling watercoffee powder was added and covered with a plate. After few minutes, the powdermight settle at bottom after essence mixing in the water. This was simplyadded to milk for milk coffee. Sugar was also added for milk coffee. For blackcoffee it was diluted, added with sugar or karupetti. Even now tea shops of Keralado not use decoction percolator. Now mosthomes have decoction percolator. The coffee powder is supplied in packs ground todecoction coffee form. It is placed in the filter, pressed a little and boilingwater is added. Here too essence goes to a bottom vessel through the percolatorand the coffee powder remains in filter. But there is a big deference in the coffeetaste- of the decoction and coffee water added in milk and prepared coffee. A slightside track- I recollect a news item appeared in newspaper before years. It occurred when Late Rajeev Gandhi visitedChennai while he was prime minister. He asked for famous decoction coffee. Theattending persons were least prepared for it. They had only kept Nescafe. The newsitem read he became impatient over the delay in providing coffee. Somehowhe was supplied with decoction coffee getting coffee decoction from famousrestaurant. Other than news item,nothing more about year, time etc. is in my remembrance. 12. strainers in bath room and wash basins Theshower employs a tiny holed filter. The waste water lines are connected to thepipe line through a strainer with medium holes for air entering the pipe line.This avoids foul smelling as well as water easy going to waste line. Bath roomcleaning liquid/Dettol is used to clean the flooring after shower or bath byall taking bath. 13. The filters in the air conditioners. Ourwindow air conditioners employ air filter. These filters are easily removableand washable. Periodically they have to be cleaned and washed for removing ofdusts. We can clearly observe freshness on the day filters are cleaned andplaced. These filters are fibre filters. 14. Netting in the windows for preventinginsects – insects screen or simply mosquito net In simplelanguage though we say mosquito net, it is not permitting large insects also.Various forms are there with fibre or metallic mesh. Mostly opening and closingtype frames fitted with metallic mesh are provided inside of windows in thehouses. Surely it is a dust filter also. This also requires periodic cleaning.Normally a brush for mesh cleaning is supplied along with. Just brushing, wecan observe tiny particles of dust falling down filtered by the mesh. Once amonth cleaning is sufficient. Earlier the mesh was fixed with windows in thepressing type arrangement. 15. Filters for extracting In allayurvedic preparations of oils, the extraction is made using filter. Thepreparations are made using various herbs and plant leaves etc. They areremoved off after taking essence by filtering. Staining type filtering is used 16. Nets for fishing, over the open wells Fibrenets are used for fishing. In open wells nylon net is provided to avoid fallingof leaves. Nowadays metallic net is provided with fitting arrangement, andopening provision. Motor is fitted to lift water. When necessary opened thesmall provision, and water is fetched using bucket and rope. Metallicnets are provided in fencing by many. Above the grill work net is provided to avoid the entrance of cats to porticonowadays. In olden days metallic net wasfitted over window air conditioners in buildings. 17. Water filters. Earliertype water filter drums had either one or two filters fitted inside. Water was filledand after sometimes collected through a tap. Impurities were absorbed tofilters. Once in three days the filters were cleaned. Now mosthomes have ROS system deploying paper and carbon filters. Now inChennai many places have ROS water supplied by municipality free of cost. Oppositeto my home about 20 metres away one unit is there. Servant lady brings water inpots. Quality is found very good. 17. Filtering in selection etc. Allinterviews, tests are filtering to get the best suited condition for theirrequirement. In the selection two IAS IPS etc. three types of filter isemployed, First exam, 2nd exam and then interview. I havenot covered the different types of filters employed in factories in production of cotton, cement, wheat flour etc.In large temples the hundiyal coins are separated using sieves. -- You received this message because you are subscribed to the Google Groups "Thatha_Patty" group.
