Maple Syrup: New Producers and Hobbyists

General Overview

Maple sugaring can be very enjoyable; however, it is labor intensive, especially for the small scale producer or hobbyist because the equipment is smaller. If a hobbyist has access to healthy, tappable sugar maple trees, the first consideration is the ability and time to evaporate the sap to finished syrup. You must be honest with yourself about the amount of time you not only have available but are willing to spend evaporating. The syrup will run when the weather is right, not when it is most suitable to you. You may have numerous good runs during a one or two month sugaring season. Unless you pull the taps early or dump some runs, you will have to process them all. Sap can only be stored for a limited period of time before spoilage. Spoilage occurs faster during good runs because the weather is warm (usually 40 degrees or more). Sap is essentially a light sugar solution that is wonderful microbe food. If you work on a farm, in your own business, or can work your schedule around good runs, then sugaring may be for you. Many dairy producers and farmers are also sugarers because this works well with their schedule.

Getting Your Feet Wet

Alternative 1

Hobby maple syrup operations can vary greatly in size. For a producer that taps 10 trees or less, a pair of very large cooking pots may be sufficient to handle your evaporation. This method is slow and is best suited to someone that wants to learn about sugaring. Remember that 10 trees may make 20 gallons of sap in a good run and unless you have really big pots (apple butter or butcher kettles) or alot of time, production may be slow. A flat evaporating pan, which larger operations would us as a "finishing pan," will substantially increase your rate of evaporation in pots. These pans can be purchased new or used from a sugaring equipment supplier or manufactured by a sheet metal worker. A hobbyist should try a small-scale operation for at least a year before considering the large investment necessary to start even a small sugaring business.

Alternative 2

If you live in a maple sugaring area, you may be able to tap trees and sell the sap to a neighboring producer. A producer that wants to increase production may be willing to buy sap instead of adding taps. The purchase price will be low (in the range of $0.10 to $0.70 per gallon); however, you can develop a good collection network and perfect this end of the business prior to investing in evaporation equipment.

Sugaring season may start as early as late-January. The primary trigger for good sap flow is warm days and freezing cold nights. Either ask your local Extension Agent or the Maple Syrup Team about the progress of the tapping season. Starting early in the season is usually good for sap quality and quantity but can be very frustrating when continuing cold conditions leave you for days with little or no sap.

Tree Selection

For the hobbyist, several types of maples can be tapped: sugar, black, red, silver or Norway. Sugar and black maples are the best; however, red maples are also used to some extent commerically. Select trees with large canopies with trunks greater than 31 inches in circumference (10 inches diameter). Avoid trees that are not vigorous or that have large defects. These trees will produce low sugar content sap and may be excessively stressed by tapping.

Tapping

Sugar producers use a 7/16 inch drill bit to tap trees. The holes are usually bored to a depth of about 2 1/2 inches and at a slightly upward angle so that the tap drains well. Care should be taken not to "round out" the hole. Traditional guideline suggest that tap holes be six inches to the side or twenty four inches above or below unhealed tap holes. Tap holes will be healed in 2 or 3 years. Be cautious of clustering tap holes in subsequent seasons. Traditional guidelines allow up to four taps in big trees; however, conservative tapping allows only 2 taps even on very large trees. Producers currently follow both guideline. Large trees with fewer taps tend to produce more sap per tap than when more taps are used, so the decision on which set of guidelines to follow is complicated. Both traditional and conservative tapping guidelines are included in the table below.

while visiting a mountain, John approximated the angle of elevation to the top of a hill to be 25 degrees. Alfter walking 350 fe
strojnjashka [21]
There are several ways of going about this problem, but just know that it all boils down to triangles and the rules/laws of triangles.
So we start by making a large right triangle, because the hill is vertical with the horizontal ground, with 25° as the left angle (where John looks up to top), 90° is the right angle (where ground meets hill base). So we see that the top side of the triangle is the hypotenuse, and equals the line of sight from John to hilltop.
Now we've got additional information that if John walks 350ft towards the hill, his angle of elevation increases by 14. So that = 25+14 = 39. How does that possibly help us?? Well now we can make 2 triangles inside of the one we've already made. So that now we have the triangle base split between the left angle of 25° and where he stopped 350ft to the right of that.
Now the supplement of 39 is 141, and the remaining piece of that too left triangle = 180-25-141 = 14. What does that mean? Well now we have a triangle, where we know all 3 angles and 1 side --> we can find another side by the law of sines:
If a, b and c are the lengths of the legs of a triangle opposite to the angles A, B and C respectively; then the law of sines states:
a÷sinA = b÷sinB = c÷sinC
We really need the hypotenuse to then find our hill height, so we'll make hypotenuse = side b in attached image. That being so, then its opposite angle (B) = 141. And the top right angle (C) = 14 with its opposite side (c) = 350ft.
Now we only need b÷sinB = c÷sinC
So b/sin141 = 350/sin14 --> b = 350sin141/sin14 = 350×.63/
b = 220.3/.24 = 910.47 ft
Now that's our hypotenuse, so using our original large right triangle, we can use right triangular trig. to solve. Let's make the right side, our hill height, equal to x.
Sin ¥ = opp. side / hypotenuse -->
Sin ¥ = x / hypotenuse
Sin25 = x / 910.5
x = 910.5×sin25 = 910.5×.423
x = 384.8 ft

i know this is probably simple but ive forgotten how to do it and i cant find it in my notes help appreciated!
Soloha48 [4]

Answer:

? = 13.6

Step-by-step explanation:

the angle between a tangent and the diameter = 90°

Then the triangle is right with legs 2 × 6 = 12 and 6.4

using Pythagoras' identity in the right triangle.

the square on the hypotenuse is equal to the sum of the squares on the legs , that is

? ² = 12² + 6.4² = 144 + 40.96 = 184.96 ( take square root of both sides )

? = \sqrt{184.96} = 13.6

Which of the following sets is NOT closed under addition.
Veronika [31]

Answer:

Step-by-step explanation:

The odd numbers.

Suppose you have 31 and 27 when you add these two together, you get 58 which is not an odd number.

If you need a more mathematical proof, you could do it this way.

2x+1

2x is even. Anything multiplied by 2 is even. When you add 1 you get an odd number

So continue on

2y + 1 is the other number.

2x + 1 + 2y + 1 = 2(x + y) + 2

2 (x + y ) is even. When you add 2 to it, nothing changes. The result is still even.

When I am multiplied by myself, I
cestrela7 [59]

Answer:

21 & 22

42.25 ÷ 2 = 21.125.

21.125 rounded to the two nearest whole numbers is 21 and 22.

21 and 22 are the closest integers to 21.125.

The answer is 21 and 22.

Hope it helps!
