  • DIY Vacuum Chamber for Sous Vide and the Kitchen

    I don't have that one anymore but it's really quite easy. If you buy an old food-saver unit and fish out the sealer assembly all you need to do is remote the wires ( power and switch ) and your done. You put the food in the bucket, lock the foodsaver down on it like you would in its normal use then vac down. Seal. You'll have to use foodsaver bags though as they have a textured side that allows the bag to draw down. I made another unit that I use over pots and pans. 1/2 lexan with the underside laminated with a sheet of 1/8 in clear silicone mat. It will seal against the rims of most pots, bottles or pans. Good for removing air while cooking or sealing. I that one I use 1/4 in stainless steel dowel through an o-ring bulkhead and actually press the seal button on the sealer. Wires run ...

Wires run up through the center. As an example: the other day I was involved in a French Omelette competition. I wanted the finished eggs to look like a sheet of cheese so I beat them up with an immersion blender. That puts a load of air in them which will play havoc with texture. So I dropped on my lid, gave it some vac and out came that air quick. I was the ready to cook with out haveing to use a dedicated vac chamber. You'll need to cut down the sealer bar from a standard foodsaver to make one of these. Easy.

  • DIY Vacuum Chamber for Sous Vide and the Kitchen

    Since you're using a pan for a chamber the sealer is going to be tough to modify. I used two stainless steel chafing dishes one in the other as a chamber and cut out the top cover and added the Lexan sheet to that. Silicone sheet on the sealing lips provided the seal. That gave me a solid tight chamber 11 inches by 18 and 9 tall. I did not put any gauges or nipples on the top and chose to port the hose barb through the back side. That leaves the top clean and free of hoses and fittings. I used an Edwards M8 pump which will pill 7 cfm and down to 10 microns or less. The pump runs to a 250 ml trap with silicone gel in it. The top of the trap has the gauge ( electronic set to microns ) and the continues to the chamber. I bought an old Food Saver vac and pulled the seal bar assembly out...

The top of the trap has the gauge ( electronic set to microns ) and the continues to the chamber. I bought an old Food Saver vac and pulled the seal bar assembly out of it and mounted it in the chamber. I modified it to 6 mm heat strips. I remoted a heat control switch to the front of the chamber. To use I put the food in food saver type bags ( must have the diamond ripples ) and lock it into the food saver seal assy. is the chamber. I place on the top and crank down the chamber. When satisfied with the vac I operate the heat bar via the remote dial. Works well and will crush a steak if you pull it way down. Prior to that I used a clumsy O ring rod and seal to operate a bag pull inside the chamber. It worked but ziplock bags fail after a short time.

    Alternative to the Elizabethan Collar

    Be careful. Although this looks like a great idea it really is not. I've worked with E-collars for 30 years and substitutes like this one usually result in failure and unnecessary auto-trauma what you wish to protect. In the case sited above if the injury were on the face the cat could easily rub it or get to it with its real limbs. If the injury was on the back half or underside of the cat you might as well have so collar on at all. As for stress..what stress? A successfully treated cat is the least stress you can apply. NO one likes the E-collar but they are designed for a purpose: To work. The "alternatives" don't work. I'll be re-suturing a dogs ear in an hour. It's a mess. The owner took off the "stressful" E-collar and substituted an inflatable collar on the ad...

The owner took off the "stressful" E-collar and substituted an inflatable collar on the advice of a pet shop ( that got the money for the collar ). No we have a horribly opened incision, infection galore and an unnecessary bout of anesthesia. That folks...is stress.
