The sorption pump is a vacuum pump that creates a vacuum by adsorbing molecules on a very porous material like molecular sieve which is cooled by a cryogen, typically liquid nitrogen. The ultimate pressure is about 10 −2 mbar. With special techniques this can be lowered till 10 −7 mbar.
Table syrups are often used as a cheaper alternative to maple syrup, with, as of 2015, prices of table syrup, $2 per litre ($8 per US gallon), being 5-8 times lower than those of maple syrup, $11–$16 per litre ($40–$60 per US gallon). [7]
Single-stage vacuum pumps typically produce vacuum to 35 torr (mm Hg) or 47 millibars (4.7 kPa), and two-stage pumps can produce vacuum to 25 torr, assuming air is being pumped and the ring-liquid is water at 15 °C (59 °F) or less. Dry air and 15 °C sealant-water temperature is the standard performance basis, which most manufacturers use for ...
A sugar maple tree. Three species of maple trees are predominantly used to produce maple syrup: the sugar maple (Acer saccharum), [5] [6] the black maple (), [5] [7] and the red maple (), [5] [8] because of the high sugar content (roughly two to five per cent) in the sap of these species. [9]
The sugar maple is one of the most important Canadian trees, being, along with the black maple, the major source of sap for making maple syrup. [1] Other maple species can be used as a sap source for maple syrup, but some have lower sugar contents or produce more cloudy syrup than these two. [1]
A vacuum ejector, or simply ejector, or aspirator, is a type of vacuum pump, which produces vacuum by means of the Venturi effect.. In an ejector, a working fluid (liquid or gaseous) flows through a jet nozzle into a tube that first narrows and then expands in cross-sectional area.
The vacuum system is enhanced with an additional vacuum pump, specially designed for the hopper. The hopper is closed and is connected to an upstream reservoir. The vacuum present in the hopper allows filling product to be drawn into the filling machine from the reservoir. The filling product is also intensively evacuated.
A peristaltic pump, also commonly known as a roller pump, is a type of positive displacement pump used for pumping a variety of fluids. The fluid is contained in a flexible tube fitted inside a circular pump casing. Most peristaltic pumps work through rotary motion, though linear peristaltic pumps have also been made.
