  1. "La Gaetana"

    Near the crossing between Phuket Road and Ong Sim Phai Rd. (Not far from Robinson)

    The place is very well decorated. Gianni, the owner from Pompei, is a character. The food is good.

    If he can fill his restaurant (and he apparently does, without advertising) why should he lower the prices?

    Better make a reservation: 076 250 523.

    Wed. closed

  2. Oil extraction is most efficient by Hexane solvent,

    which anyone who has smelled rubber cement knows.

    Hexane use and purchase in Thailand requires a hazardous chemical permit.

    Any oil containing seed or plant fiber can be processed.

    Other common solvents work in the same way,

    Petroleum Ether

    Ethanol

    Methanol would be much slower to absorb the oil, but would work eventually

    Hexane is preferred because it has

    very aggressive solution rate

    low boiling point 70C

    and low heat of vaporization 70 cal/gram,

    minimizing the solution time and heat energy necessary to distill the solvent off the oil.

    The process equipment is six sealed tanks,

    connected in series with the solvent counterflowing against the seed cake.

    Clean solvent is passed through the tank with the least oil content,

    then progressing through the tanks with increasing oil content,

    until the final tank has fresh seed cake with all the oil content,

    while in the final tank the solvent is heaviest in dissolved oil content.

    The mixture of solvent & oil then is heated to boil off the solvent,

    while the oil does not boil at that temperature.

    The solvent vapor then is chilled to condense back to liquid,

    and comes around for another run.

    If there are no vapor leaks, the solvent is used an unlimited number of times.

    If there are vapor leaks, there is a fire hazard.

    When the seed cake is extracted six cycles,

    it is heated to drive off all the solvent,

    making it completely solvent free and almost perfectly oil free.

    If the six tanks in series is more plumbing and valves than you want to mess with,

    you can still get all of the oil out by soaking in a greater volume of solvent for a longer time.

    but the greater the number of tanks the more complete the extraction with less solvent flow.

    and therefore less heat energy used to distill.

    Since the operating temperature is so low, only 70C for Hexane,

    and similarly low for the other solvents,

    the heat energy could logically be drawn from the waste heat flow of another process.

    Expensive boiler fuel is not necessary...cheapest field or forest boiler fuel available.

    Mechanical extraction is also used,

    but a significant percentage is still left in the seedcake.

    whereas solvent extraction leaves very very little behind.

    This is a heavy auger screw, forcing the oil cake into a barrel of decreasing diameter.

    Near the small end of the barrel, the oil leaks out tiny slits, while the seed cake exits out the far end.

    If you have unlimited budget for fancy weld fabrication and gas compressor,

    then the Supercritical Carbon Dioxide extraction process is just beautiful,

    but it operates at over 2,000 psi, that's not a typo, three zeros.

    136 bar.

    Over 5 times the pressure rating of an LPG Propane tank.

    The liquid CO2 passes through the seedcake,

    and when both are separated to another tank,

    the liquid CO2 is expanded to gas, leaves the oil mixture, and is compressed back to liquid for another pass.

    One significant feature of this process is that there is no possible residual solvent in the dry seedcake.

    and the operating temperature is near room temperature.

    Carbon Dioxide is commonly available, cheap and safe.

    Thank you WE.

    I guess I don't start a new hobby then :) .

  3. i know absolutely nothing about this plant or have any answer to your question, but i snipped this piece from wikipedia, just so's you're aware....

    The toxicity of raw castor beans due to the presence of ricin is well-known. Although the lethal dose in adults is considered to be 4 to 8 seeds, reports of actual poisoning are relatively rare. According to the 2007 edition of the Guinness Book of World Records, this plant is the most poisonous in the world.

    Poisoning occurs when animals ingest broken seeds or break the seed by chewing: intact seeds may pass through the digestive tract without releasing the toxin. Toxicity varies among animal species: 4 seeds will kill a rabbit, 5 a sheep, 6 an ox or horse, 7 a pig, 11 a dog, but it takes 80 to kill a duck. The toxin provides the castor oil plant with some degree of natural protection from insect pests, such as aphids. In fact, ricin has been investigated for its potential use as an insecticide. It is also the source for undecylenic acid, a natural fungicide.

    Thanks turnpike. I red that also. And many other websites.

  4. I started to roast coffee in a wok about 20 years ago.

    Then I had a small roaster (250 gr).

    Now I have a bigger one. Roaster that is. (2.5 kg)

    I buy most of my coffee from the farmers, in the hills between Ranong and Chumphon. Robusta.

    I am far from being a professional. But being better than Star_ucks, is fairly easy.

    Is there anybody in Phuket, who knows a lot about roasting coffee or wants to make his own roast?

  5. Parlai Seafood.

    Chaofa East Road from Hayaek Chalong direction Phuket town. Turn right at the traffic light direction Zoo. Follow the road till it ends.

    Mostly Thai people there. Some Expats.

    I love the Pla Samlee (Cotton fish)with green mangoes.

    In the same region are 4 or 5 other seafood restaurants.

    Roi chang hoo!!

  6. Call Mr. Manit: 081 270 67 76

    - very good driver

    - clean car

    - speaks good enough English

    - very reliable

    - 800 Baht

    if have used him for years, for my guest.

    Tuk-tuks: No f...... way.

    Green licence plates: hel_l no.

    Minibuses: Cheap, but can take you several hours, if they drop every passenger at a different hotel.

    Meter Taxis: If you're lucky, you may get a good one.

  7. I'm considering doing a trip to Europe for both leisure and to get a Non immigrant O multiple entry Thai visa (for visiting friends).

    I've heard Stuttgart and Amsterdam are good places to get such a visa, but I was wondering about Switzerland.

    On this page: Honorary Thai Consulates - Europe & UK it says there are three honorary consulates there: Basel, Geneva, Zurich.

    Has anyone actually been able to easily obtain the visa from any of these particular consulates?

    I get my non imm o multiple from the Thai embassy in Bern.

    Quick and friendly. No pompem.

  8. Hi all!

    I want to start some food products, where I could need some liquid smoke, but I couldn't find it on KPG.

    Is there any place on samui where they sell that?

    It comes in 150ml bottles.

    Cheers

    Ask Don in Rawai.

    His spare ribs used to taste like liquid smoke.

    I guess some people must have liked that.

  9. Anyone can advise as to where to buy pool chlorine and how much for the big tubs? Thanks.

    Phuket Water Quality

    Vichitsongkram Rs.

    Tablets: 50 kg       5'350 TB

    Granular: 50 kg      4066 TB

    As far as I know, Supercheap has neither tablets nor granular.

    But Soda (for ph adjustment) and Aluminium Sulphate (as flocculant) and Copper Sulphate (Algee killer) I buy at SC.

    If you have any better prices, pls let me know.

  10. Crazy idea - not mine - but has anyone in any rural area done this?

    Maintaining I am not too worried about - but finding someone who knows building/digging one is

    COSTS?????

    Contact Desjoyaux.

    When I built my pool, I tried to get 5 offers.

    Only Desjoyaux wrote a detailed offer.

    He built my pool.

    In all the markets that I have been to here in Thailand, people sell either fruit or vegatables, but never both. My question is why? It seems there are many things here that are taboo and I quess this must be one of them.

    exactly which markets have you visited? almost all fresh fruit markets offer plenty of both, not either or, but both veg and fruits....

    have the markets changed so much in certain part of thailand, that farmers focus on selling either or, but not both....?

    i could be the only ryp van winkle alive today.... lol

    Of course, all the markets sell fruit and vegetables. But the sellers sell fruit or vegetables. Guess have to ask a fruit seller why he doesn't sell veggies, and a veggie seller why he doesn't sell fruit.

    I asked my wife. She said: Because Thailand is very hot, the veggies have to be sprinkled with water quite a lot, to keep them fresh. But fruit should not be sprinkled or touched with wet hands. 

    It has nothing to do with ghosts or spirits or any religious believes, animistic or others.

  13. There is one up on a cliff I think after Karon on the way back towards Phuket town, looks out over the sea from up high, sometimes has a band and is cheap enough. Beautifull. Other wise Jazz restuarant is good in Patong, nice beer too, and the band is awsome. Jazz is up near Andaman road on the corner to go around to Andaman Resort.

    I like Kaneng Pier in Chalong. Been there many times. Never diappointed.
