Using ThriftyVac® to Vacuum Pack Food Surrounded by Fluids
Maximize the Life of your ThriftyVac® Outer Bag
The best way to keep your pecans and nuts fresh
My latest invention is a vacuum lid that lets you vacuum pack any size jar or bowl that you already have.

Kickstarter actually approved my project as I was writing this post, and it is now live. (that is why the original link did not work).
This is the third in our monthly series of tips on getting the most out of your ThriftyVac® system.
You can best vacuum pack food with fluids, such as gravy, by using a book or thick cutting board to elevate your ThriftyVac® unit. Doing this keeps more fluid inside your food bag and maximizes the vacuum. This is illustrated in the YouTube video: https://youtu.be/o_Ww2FSi1zA.
Since only one inch of the food bag’s seal is open during vacuuming, bags vacuum packed with ThriftyVac® retain more fluids that might otherwise be drawn out of the bag. Also, the ThriftyVac® Housing elevates the Check Valve’s exhaust port three centimeters above the base of the outer bag to keep fluids inside your food bag. This is very important for sous-vide cooking and for vacuum packing moist or marinated foods. Finally, you can further enhance fluid retention by positioning the ThriftyVac® unit near the edge of a thick book or cutting board and letting the food bag hang over the edge. Doing this, in combination with the elevated exhaust port, maximizes fluid retention and helps keep the vacuum pump clear of any fluids that may be drawn out of your food bag.
The process is simple. Vacuum pack your food as usual, stopping when fluids just start exiting the one-inch open segment of the food bag's seal. Close the open segment of the seal, and withdraw your vacuum-packed food bag. The complete process is illustrated in this YouTube video.

This is the second in our series of monthly tips on how to get the most out of your ThriftyVac® products.
You can make your ThriftyVac® outer bag last longer (over 50 cycles) by applying a 3 x 2 inch strip of clear packaging tape on the outside as shown in this YouTube video: http://youtu.be/tbIHhMdgfNk. All ThriftyVac® systems are now shipped with tape-reinforced outer bags.
We chose to make ThriftyVac®’s outer bag (the bag that serves as a flexible vacuum chamber) out of thin polyethylene (PE) so that it would:
- closely conform to the contours of your food bag when vacuumed, thereby minimizing air inside your food bag
- puncture cleanly when we made the hole to reinsert the Check Valve. (Bags made of stiff plastic materials do not puncture cleanly, but rather splinter).
However, the outer bag gets highly stressed during the vacuum-packing process as it is drawn down tightly against your food bag and the ThriftyVac® Housing. Highly stressed areas may tear with repeated use, requiring you to replace the outer bag.
You can greatly extend the life of your outer bag by reinforcing the most highly stressed area with high-strength packaging tape. More specifically, you can apply a 3-inch piece of clear packaging tape over the area of the outer bag that covers the word “ThriftyVac®” on the Housing. We recommend using Scotch’s “Heavy Duty Shipping Packaging Tape,” because it is 20 times stronger than acrylic tape. If you don’t already have such tape, then you can buy a 22-yard roll on Amazon for $3. (We have no promotional agreement with either Scotch or Amazon.)
This tape is 1.88 inches wide and easily covers the most highly stressed area of the outer bag.
How to Apply the Reinforcing Tape
You can apply the reinforcing tape most easily when the outer bag is empty and lays flat. (You can remove the Housing from the outer bag by simply pulling up on the Check Valve, using a twisting motion.) You should apply the 3-inch length of the packaging tape 4.5 inches from the right edge of the outer bag, and 0.8 inches away from the top, as illustrated in the figure below.
The YouTube video below demonstrates a simple and effective way of cutting and placing the strip of reinforcing tape on the outer bag.
After placement, run your thumb over the reinforcing tape, pressing it hard against the outer bag, because that ensures good adhesion. Use your thumb and fingernails to press out any bubbles between the tape and outer bag.
All ThriftyVac® systems are now shipped with tape-reinforced outer bags.
Next month’s tip will illustrate the best way of vacuum packing moist foods, and retaining their fluids inside the vacuum bag.

I tried to think this through. I reasoned that storing my pecans in a TV2 bag might be much better than storing them in a vacuum jar because the TV2 bag minimizes the empty space surrounding food and thereby minimizes dehydration.
But that was not enough. I also needed to keep the pecans from decaying, and this required refrigeration. I did both, and it worked. I now vacuum pack my pecans in a TV2 bag and store them in my refrigerator. My wife now tells me that I am gaining weight.
